Update!!! My order came in like 3 days! Super fast shipping! I got it installed in about an hour. But HUGE piece of advice. The screw, metal clip, bracket...DO FIT IN THE HOLE...All you have to do is (clean the surface obviously) and the antenna with the screw, bracket, everything goes in the hole. All you have to do is tighten the screw down from the inside to get it snug! This will save anybody who tries to do this a huge amount to time and effort (and tore up arms and fingers trying to assemble the bracket/screw under the ceiling. So. Recap. Keep the antenna as it ships. Completely assembled. Pull the old one like you did in the video. Feed the wires and plug it in like you did. BUT keep the antenna 100% assembled (DO NOT TAKE THE SCREW OUT) it'll all fit in the hole and mount to the roof and just tighten the screw! That's it! Thank you though for the video and also the link to purchase the part! Cheers mate! 🍻

[@Jsean]

Glad it worked out! Thanks for the tips!!!

[@segbachan5123]

Steve thanks for the tip.i been trying to tighten mine but it looks like it's just tightening on the bolt..the hole looks messed up since mine was backed into the garage door..I will try again to see if will work

[@Steve_Sinatra]

@@segbachan5123 not sure if there is damage to the home you feed it into. But the main thing is to hold it from up top and make sure it is pressed all the way in before you start tightening it. It's a small lip that starts expanding out that makes it snug. So don't screw it down a lot if it's not snuggling down right away. It doesn't take much screwing in. If it isn't snuggling down right away the lip didn't catch the under side of your roof. Stop screwing and smash the bracket back together as best you can and try again. Again. It doesn't take a lot of turns of the screw. So make sure the antenna is pressed all the way in and the lip of the bracket is catching the under side of the roof. Good luck mate!

Did you use aftermarket or where did you get it

[@Jsean]

I used an aftermarket. It used to be cheaper though. I contacted the seller and they stated they are authentic but the price went up so I’m not sure. You would have to verify this with them though as I am in no way affiliated with them. Not 100% sure of the actual reason but I know I helped them sell a lot of these since I made this video so I’m assuming that’s why the price went up a little. I put the link in the description of where I got mine on eBay. It is not an affiliate link or anything like that. I just wanted to help others out. I hope it works out for you!

I'm glad you posted this video...! My xm radio reception has been very week lately..! Plus, now that I've looked into this, I realize now that this is the source of my occasional water leak, but I didn't realize it was coming from this antenna mount...!!!! (Long story) I was able to remove the old antenna with difficulty and ordered a replacement. I"m not sure I have a complete plan to re-install the new antenna to prevent interior water leaks. I do intend to apply grease or Vaseline on the two rubber seals. I would like to plug the rear facing "water leak hole" with RTV sealant. I think this antenna unit should't need a leak hole. Comments..? 2006 Chevrolet Silverado ext cab 4 door, 2wd, Z71 suspension, posi-traction near axle, Michelins. Tows a 24 foot camper VERY good!!

[@Jsean]

No problem! I’m glad you figured out where your leak was coming from. Apparently it’s a common part that tends to fail quite often. That minor water leak can cause loads of costly damage. I honestly don’t know the purpose of that hole but on my new one it’s facing down so I don’t see a need to seal it but if yours is on the top side I don’t think that’s a bad idea at all. Good idea with the grease or Vaseline. Good luck with the install and I hope that it all goes well. Let us know how it worked out if you can 💪

[@wolverinestuhs]

Thanks for the video I have a 2017 1500 Silverado, I put some clear silicone in the gap probably meant to be the drain hole if so its backwards or just bad design anyway temporary fix. So from reading other posts about dealer pricing this part isnt under warranty cause I let the dealer where I got the truck from know about it they want me to bring it in if its not covered then ill just do it myself. Don't make sense that the hole is on the angled side allowing water to flow into it but it is so so thanks again for the tutorial. 👍👊

[@Jsean]

No problem, glad it was helpful. Yea it sucks I hope your silicone holds up. The design just doesn’t make sense to me and so many people end up having the same problem. Some were told by the dealer that it was $5-600 range to replace it. The bad part is when the water comes through and hits your headliner. You’ll end up messing up a lot more than that antenna. Good luck with everything and nice truck. 💪

@@Jsean it's back together now. First things I noticed was the musty smell and then I had water dripping from the driver side sun visor. I installed a new shark fin antenna along with some silicone for good measure. I then cleared the sunroof drains and applied silicone to the rear cab vents which were also leaking. It's been raining the past couple days, I've been checking and no water in the cab so far so hopefully I got it fixed.

[@Jsean]

SMH I agree. Especially with the hole placement. Makes no sense at all. Plus the dealership charges way too much to fix this known issue. Nice set up! Mines all blacked out too with 6 spokes but my wheels are matte black 26’s. I also have the yellow fogs. One thing I added that I don’t see in my area is the “glow tie”. A little pricey in my opinion but it ties right into your factory set up. I think it looks nice. Other Tahoe owners stop me a lot and ask about it not knowing that it’s an official GM part/upgrade. If you haven’t already try out the Chevy all weather mats too. They work great as they cover everything from spills etc.

[@jonienglish3231]

@@Jsean Yes mine came with the All Weather Mats - Yellow Chevy Bow Tie , + I painted my Calipers RED . i find the 22" Rides HARSH , Prefere the 20" on my Winter RIMS RIDES SOFTER

[@Jsean]

@@jonienglish3231 i feel like my factory 20’s ride the same and always thought those even felt a little harsh for some reason but you definitely have to be careful riding over bumps with larger wheels and skinnier tires etc. I had my calipers painted red too but I hated how it looked behind my factory chrome 20’s whenever i switched the wheels back. I had brushed 6 stars in the same wheel before i bought the matte black ones. I originally wanted gloss but they were out of stock but I sort of like it now. It adds a little bit of contrast to the gloss black Tahoe and I never have to add tire shine since it sort of all blends together now. I ended up making my calipers back to silver and then recently went to black calipers. I added some drilled/slotted rotors so I wanted them to contrast off of them since those are bright silver behind the black wheels. My factory rotors are way darker behind the wheel than these new rotors.

[@FamilyChannelfun32]

If your antenna still works fine but you are getting water take it off . Silicone the inside gasket around that bolt . You will see it . it is square and then put the bolt back on. Then lightly silicone the shark fin around the bogger outside gasket and silicone that little square hole in the back! That is what allows water to get in! I did this and it worked perfect and I have gotten a lot of rain! DRY

[@mbryant1136]

Why not just silicone around the outside of the whole thing? wouldnt that stop water from getting in? Why bother taking it apart and doing the inside ?

Krystle Torres oh no that sucks! I’m not sure but for this vehicle the antenna came with the cover. I don’t know if they would sell your cover separately. I would try to find out the part number and put that info in ebay or somewhere else to see what pops up. You can call a Kia dealer service department and let them know your vehicle year, make, model etc and tell them which part and they should be able to give you an exact part number. While your talking to them ask how much it cost and then reference what you can find online yourself as I imagine it would be a lot cheaper. Hope that helps.

Depending on where i am parked it wont seem like its calibrated until I start driving. Once i drove off it calibrated. Take a drive and see what happens. If it starts working then you should be good going forward. Hope that helps and if you can let me know what happens. 💪

Does this fix navigation issue? My Tahoe GPS shows I’m currently driving in the middle of the Gulf of Mexico (which we know isn’t true). Also, will XM radio still work? Thanks for the video.

[@Jsean]

Corey Long LoL that’s horrible. Well, based on what I saw for others and my situation it helped with radio issues, gps and water leaking into the actual cabin. I recently noticed the light was red on my rear view so one day I hit the OnStar button and customer service ran a diagnostic. They told me it was the antenna not working properly for whatever the reason and to take it to my dealer. Upon further research the part itself wasn’t too high in cost but the dealer will most likely still charge for a diagnostic, part and install so the price jumps up pretty quick. I tried to see if it was covered as a faulty part but the dealer said no. If possible I would recommend taking yours off and inspecting it. What you see here is after I cleaned it. It was corrosion everywhere and way more water and junk pouring out of it just a few days before this footage you saw. I unscrewed it all the way and looked at the board and it had a few burn marks so I knew it was the antenna for sure in my situation. My Tahoe is only a few years old so I was surprised at how bad the condition was. This one I happen to run across on eBay is a great price and shipped from Texas. If you have a different color cover you may be able to take off your old one but I’m not 100% sure as I didn’t end up having to switch covers. I hope that helps. If you can let me know what ends up happening!

@@Jsean do you have a link to the replacement antenna you used?

[@jseanspeaks]

Shelton Family hello, it should be in the description. Good luck! 👍

[@mbryant1136]

My question is, with the opening in the gasket to the front of the vehicle, wouldnt you get water in while driving in the rain? Wouldnt it be best to not have an opening in the gasket? I have a little water dripping from where the visor mounts on the drivers side, Im going to just put clear silicone all the way around the antenna and see if that stops it. My XM and Onstar is still functional. I see no need in having an opening in the gasket no matter what side.

[@Jsean]

Honestly, I don’t understand the design at all lol but based on me and many others issues it seems if there had to be a gasket opening for whatever the reason it shouldn’t be on the side the factory makes it. I imagine that like any other gasket it will start to lose its seal due to weather. Gets stiff from the cold and maybe loses its shape from the heat and after awhile the seal isn’t as tight and then water can eventually make its way in. As far as the seal being on the bottom, I’m assuming while driving the force is so great that water wouldn’t really go into that tiny hole in the gasket and if it did it would naturally work itself out by it being on the bottom. If on top the water could easily get into it especially if your vehicle was parked in a storm etc. if I remember correctly the gasket may have had channels or something inside so it wasn’t simply a hole that went strait through. Don’t quote me on that though. I believe if your antenna is still functional but water leaked through it would only be a matter of time before the antenna stopped working as water is finding its way through your gasket. If you seal it as you say I’m assuming that would work too as long as you didn’t mind having silicone around it. Just make sure you wipe around the edges clean so the silicone will adhere properly. Good luck and I hope it works out for you! Worst case scenario you at least know the culprit if the silicone doesn’t hold up. Just be careful, the last thing we all want is water coming inside. That can lead to so many other problems. Hope that was helpful!

If it says it doesn’t fit I wouldn’t take a chance. You could send the seller a direct message and ask if he has one that fits the 2015 Silverado or find the part number through your local dealership and then search for it on eBay. It’s a little extra work but better taste than sorry. Besides being a different part number I’d imagine the way you install it should be the same or generally the same.

Lately I noticed that my On-star come back online and I had free Sirius Xm. I also noticed that my GPS all of the sudden had my home address programed in it something that I never do. Even after erasing the data and double checking that the entire history was wiped out my address again showed up on my navigation, and I am beginning to be concern since during the last few months I have noticed a particular vehicle following my SUV. I checked for trackers but did not find anything so I am wondering if On-star was hacked if that is even possible. Evidently I want to disable the On-star Feature. Is this something that can be achieve by removing a fuse or do I need to disable the module ? If so is this module located being the CUE or glove box ? Do I need to open the module and disconnect anything inside or just unplug it ? What features will be lost ? It is a 2016 Cadillac Escalade Platinum. Thanks Oli

No problem and what’s up from the States! Many of these vary well may be the same but if I were you I’d call your local dealership and talk to the parts department. They will ask you for your vin number to verify it is indeed the correct part for your exact vehicle. If your antenna looks like mine then simply let them know you are looking for the part number for the “shark fin” antenna after they run your vin. From there just type that part number in eBay or the I internet and purchase only from a trusted place or seller and I’m sure it will save you some money than buying it from the dealer.
