Hello,

i have a 2009 G37 coupe with navigation, i have often on the central lcd display some sorts of distortion/fuzzing, but all equipements is wotking fine (radio, climate etc).
This issue happen only when the car is moving or when i displace the cursor on the Nav GPS map, when the car is stopped, there is no issue.

i found this topic with a similar problem:
https://www.myg37.com/forums/audio-v...av-screen.html

i'm trying to find how to acces to the part 25915-ju40a ( dvd player?), or to find someone who can help me with this issue .

Thanks

 

I can solve your problem easily. But it’ll cost you for $45.

Go on eBay and buy a new screen for $45.

 

Looking at the pics in that other thread I don't think its the screen. It's likely an issue with the AV unit itself.

 

I dont think is the screen, because when the car is stopped all is working fine, on the other thread, he talk about a cd player in the trunk

 

25915-JU40A is your NAV controller. Keep in mind your car is EU-spec (France) so the setup and configuration is different than US-spec models. It sounds like the controller is not repositioning your map-matching data correctly. Whether that is the result of a bad module, faulty wiring, or corrupt data I do not know.

What do you need "access" to do? Remove or replace the unit?
​​​​​​
Your best option would be to scour any junk yards or the internet (eBay, google, etc.) as "new" units are no longer available (these units are 10+ years old).

Do you need the NAV function? Is it something you use frequently? (In 10+ years I've never used it once, but that's me ​​​​​​) I ask, as you could try disconnecting the NAV module entirely and see how the display performs.

Unfortunately, for whatever reason, shop manuals for EU, GCC or even JDM-spec cars are not available online. I can't even begin to tell you what wires to check.
