Hi Viktor - do you have any guides to remove the bottom trims of the door on the Lexus RX350 to clean them? Multiple reports over the years from owners getting water stuck in doors after heavy rains. Water sloshes around inside doors until you stick something into the drain hole to clear the clog. I have to keep doing this now with a thin straw cleaning brush because the door drains are becoming clogged from pollen etc. I believe water is supposed to drain from the sunroof down through the doors and through a small hole located on the bottom of the doors.

[@Viktor_G_Automotive]

@@mikeg3888 hi, I have a video on how to remove the door panel. After that, plug the window switch back in and roll up the glass. Peel back the plastic Vapor barrier and you will be able to clean inside the door.

Hi Viktor! I love your videos and had a question about my 2015 ES350. It doesn't have the navigation option, only the info-tainment setup. Will this menu access work with it? Also, is it helpful to check the function check/setting menu? I'm having a problem where my easy-exit drivers seat is not function and would like to troubleshoot it. Thanks much!

[@Viktor_G_Automotive]

@@brucedraganjac9833 hi Bruce, I don’t think this method will work if you don’t have navigation, but you could try it, won’t hurt anything.

My radio doesn’t work i have an es350 2015 n it keep saying checking maps disk please wait & it would boot loop. Before the bootloop it would say something like error bring to dealership. When i disconnected battery that is when rhe bootloop started

[@Viktor_G_Automotive]

@@youngman671 might need to have the radio head unit replaced, but impossible to be sure without having a professional look at it in person.

Hi, How is your meter and acceleration screen display is different from other Lexus? Yours looks different and there is a green color too.

[@Viktor_G_Automotive]

@@padirichie6145 this vehicle is a hybrid rx450h, is yours a regular rx350? That would explain the difference.

Great video my man!! Does the same procedure applies to a 2007 Lexus LS 460 base model?

[@Viktor_G_Automotive]

@@ryandavis2623 I believe at least one of the methods will work on the LS (if it is equipped with the factory navigation system). Give it a try, it can’t hurt anything. Cheers!

Hi, the screen of my CT200h main unit switched off after I installed map update from new SD card. No sign of life , only the CD system has power on (I can insert and eject CD-s but no sound of music). Do you have some advice how to fix that main unit error?

[@Viktor_G_Automotive]

@@ToomasLaurits usually the radio head unit needs to be replaced if that happens.

[@ToomasLaurits]

@@Viktor_G_Automotive isnt it possible to repair in some electronic workshop?

[@Viktor_G_Automotive]

@@ToomasLaurits yes, it may be possible, but at the dealership they don’t do that, only option is replacing with a new or used unit. If you search around, you might find someone who repairs these units, unfortunately I don’t have that information.

I have a 2011 rx 450h. It’s got an intermittent rattling noise in the middle of the dashboard while driving, especially on rough surfaces. Is there anything I can do ? Any feedback would be greatly appreciated. Thanks again.

[@Viktor_G_Automotive]

Diagnosing and fixing a dash rattle is usually a time consuming task. You have to work methodically to find the source of the noise and then insulate the contact points with foam tape. Often the entire dash has to come out to complete the repair.

how do I update the navigation system on my 2010 rx450h lexus

[@Viktor_G_Automotive]

The dealership uses a special tool to load the update. I don’t know if an aftermarket update tool is available, I’ve always used the factory one.

[@VESELUSCHKO]

Hi Victor... I have a little problem with my lexus rx450 h 2015.. The nav display was set to show the bluetooth contact with my phone range, battery and date and month. It was an information bar at the top of the display. This bar for inexplicable reasons is no longer displayed.. Please advise me how to fix these settings. thanks

[@Viktor_G_Automotive]

Hi, unfortunately I couldn’t tell you off the top of my head and I don’t have one of those models around to check right now. Checking with your owner’s manual might be the best option at this time.

[@VESELUSCHKO]

Unfortunately, there is nothing written in the owner's manual about this kind of setup

[@miryamamar3420]

Thanks for sharing. What could cause rattling coming from the right side only over rough roads on this RX? I appreciate your help.

[@Viktor_G_Automotive]

Strut, sway bar bushing or link

[@Viktor_G_Automotive]

Not really, since I don’t know what the issue is. If everything is working properly, you don’t need to fix it.

[@NAMLE-le9uh]

Hi Viktor, hope you are good. My rx350 2013 has code 0 :EMV-M MOST. Do you know what's wrong with it? My car has no sound (I try to fix amp or fuses by myself, but to make sure what is EMV-M MOST?. Thank you

[@Viktor_G_Automotive]

MOST (Media Oriented Systems Transport) is the media communication network in the vehicle. That code tells you there is an issue, but does not specify where the issue is. Needs to be diagnosed.

[@jimjones1505]

Can u show how to update firmware on 2010 rx350

For navigation? You need a special service tool, can’t do it at home as far as I know.

[@miryamamar3420]

Hi Viktor, hope you're doing well. Is there a way to program 4 tires to this RX (Summer and Winter) so that I don't have to re-program the TPMS sensors every time I swap tires?

[@Viktor_G_Automotive]

Not possible to program 2 sets, but you could buy aftermarket cloned sensors for the other set of wheels. They will have the same ID codes as your original wheels and you will not have to reprogram them when switching from winter to summer wheels and vice versa.

[@miryamamar3420]

@@Viktor_G_Automotive I had bought a set of 8 tpms sensors, same brand and model. Could the ID codes of the installed and programmed four sensors be copied to the other four?

[@Viktor_G_Automotive]

@@miryamamar3420 It depends on the type of the sensor you bough. The OEM ones and some aftermarket ones are not programmable, they are pre-programmed with the ID that is written on them. Some aftermarket ones are programmable. You would need to look into the specific ones you bought and see what the options are.
