How to Wire a Low Cost Double-Din Head Unit with Back-Up Camera: Carzin and More

Looking to upgrade his aging car stereo. for $59 a friend found a Carzin model 7010B with a 7” touchscreen, Bluetooth, Aux in, FM, USB, a back-up camera and more! In this video I will focus on wiring in these low-cost “head units.”

I do not think there is enough appreciation for fantastic instructional videos like this. The timing, the editing, the voice, the stable volume. Thank you sir for making this video. Great Job!

Does it matter if the wire harness that plug in back of the cd player it’s wire or red or white???

[@quentinnewman5487]

I ask cuz I see his wires is red and mine silver and it didn’t work for me some reason

[@carmennance1254]

Thank you so much for this detailed video that included troubleshooting! Especially since I faced the same issue with the quick splice connector | used on my truck's reverse light. After the 16-14 gauge quick splice connector I originally used failed to make a proper connection, I switched to a 22-18 gauge quick splice connector and it worked just as designed. I wish more installation videos included troubleshooting. For other people attempting to install their own stereos and back up camera: your vehicle's wiring diagram colors may be totally different than the aftermarket connector(s). Google your wiring diagram/connector to cross-reference. My truck's OEM connector had less wires than the aftermarket connector, so I capped the unused wires.

[@blacklionrock]

This video is probably the most detailed install video I have seen to date on how to install these radios. The color diagram is different for each style. Nothing is universal except the vehicle aftermarket harnesses. Thank you for your hard work.

Works pretty good, don't know how long it will last but we'll see. Pretty happy with the cheapo, backup camera works and pairs up with my phone. You do have to import your phone book every time but it only takes a few seconds so no biggee for the cheapo.

thx mate , I was wondering wat the red wire next to the yellow rca reverse plug. powers leds on reverse camera!

[@billma8]

You should never under any circumstances wire nut in a car. Wire nuts are designed for line voltage solid core wires in buildings. With stranded wires, you cut strands when you tighten them which is just asking for electrical gremlins down the road. Eventually they vibrate themselves free due to the cut strands or just get a bad connection. Tap splices are also asking for problems. Vibration can cause the strands to get cut and over time fail/work intermittently. Butt splice if you want it done quick, just make sure you fold those wires back on each other. The best way is to lineman splice the wires, solder, then heat shrink. That connection will last forever. Also, spend 15 bucks and a little bit of time to put those leads in wire loom to prevent shorting.

[@TheOriginalMechanic]

Thanks for taking the time to share your knowledge of professional car audio wiring. In my last career as an industrial electrician, it was standard practice to wire nut 480V stranded wire motors to into stranded 480V factory wiring. We always finished by taping the connection with Scotch 33 electrical tape. The conditions were wet, hot (or cold) and often with vibration. A french fry factory. They held up well. Note in the video that I taped the connections with Scotch 33. No worries.

Hey! Thank you so much. It was the only video really helpful for me, and It works that make me so happy.

[@vconrad607]

Great video. Thanks. I would just add that many of these have different names, but same exact set up. So some of the wires are colored differently. I would suggest to anyone following this video to install theirs to only pay attention to the terminal designation numbers A1, A2, A3 etc. Which brings me to my biggest question on this unit. The A1 terminal, in my case a pink wire, is labeled "Parking Sensor Control Wires +12v". Which really throws you off considering it's labeled +12v and everywhere you read up on it people say it's a ground from parking brake. So it's a bit disappointing that this video has everything I needed except for that one detail because he never uses the A1 wire. I'll be hooking this up today, and get back with the results. I'll try grounding the pink first before I go and throw any volts at it.my objective is.to ground it constantly so the kids can watch it. Kinda the only reason I got a radio with video player in the first place.

[@TheOriginalMechanic]

Thanks for clarifying the purpose of this wire. The explanations on the wiring diagrams on these units are disappointing. But I agree with the intent of that parking sensor wire: To prevent the driver from viewing a video while driving. Maybe a portable DVD player for the kids in the backseat would be a better idea.

Oh god 😂 wire nuts 😂😂😂 this guy is an expert 👌

[@brucebeverly2629]

No, no! Wire nuts are for dry, stationary appIcations such as house wiring inside junction boxes, light fixtures, etc. In automotive applications, the vibration and humidity will cause wire nut and crimp - on connections to corrode and fail over time. The wiring harness connections should ALL be soldered and sealed in heat shrink tubing, if reliability matters at all to you.

You could also replace the rear camera with a TV box or any video source going into that same video input if you want to use it as an in dash TV monitor. Just install a switch to connect and disconnect the A2 back in wire to switch video mode on and off. Works great in my SWM 7805 head unit installed as a small TV monitor at home. I think all these MP5 car radios are pretty generic so it would work the same way with all Chinese models. However, the parking brake wire disables the auxiliary input so the audio is cut whenever the rear camera is on. Is there a way to enable camera or video without the audio and radio functionality being cut off, say to watch from a TV box connected directly to camera input and audio aux input?

I had a unit in the car and it didn't work so I bought a single din from a garage sale. I put it in and did all the wiring and it worked great. After talking with my wife we thought I should get one that would allow a backup camera. So I got this one and put it in, wiring and all. I have everything wire up correctly, as far as I can tell. The camera light even comes on when I put it in reverse but nothing comes up on the screen no matter what I do and some of the settings still won't save and are reset every time I start the car or turn it on. So if I turn it on but not start it I can change the setting but once I start the car they reset again. Like time, preset radio stations and eq settings.

[@TheOriginalMechanic]

The back-up 12V has to get both to the screen and the camera. It sounds like it is getting to the screen, but make sure it reaches the camera. As far as the video from the camera, just make sure the yellow jacks are all still plugged in, from the camera to the long wire and at the cam in on the display unit.

[@willyfox69]

Ok question. I didnt connect the two red wires on the long video cable, is this the cause that it doesnt start up automatically when putting my car into reverse?

[@TheOriginalMechanic]

Yes. One end of the red wire needs to be connected to the 12V wire at one of the back-up lights. the other end connects to the gray wire on the monitor end. Then when you shift into reverse 12V will arrive at the monitor and it will show the reverse view.

[@willyfox69]

@@TheOriginalMechanic Ok thats what I thought when I saw your video. I thought the long video cable was just a standard cable for many models of cams, where maybe some dont have a 12v wire so it has to run via the video cable. If only I knew this before I finished the job, hahaha, now Ihave to once again dismantel a few things to do the job correctly. Mr. Original Mechanic, thanks for your input. By the way, Ive also learned that mirror linking isnt always as straight forward as it seems. Not only the debugging story, but with many modern phones, you must change the display settings to basic. In my case, a samsung s7edge only works when the display setting have been turned down. Oh by the way, the S7 of mine has android 8, my new phone S9+ wont work for mirror linking on this model Radio.
