I have the stock Navi in my 03 G35 sedan and the only time the navigation system seems to work is when its hot outside, other than that anytime I pop it up it doesnt turn on? Has anyone experienced this before or know of a fix for it? I used to think it was loose connection or something but any day that its hot its worked for me so I don't know how to fix it as I'd like for it to work everyday.
Any info is appreciated...

Thanks

Could be something loose, and taking it apart to find out will only make doing installing a replacement easier if it's required.

 

is it completely blank or stuck on a screen like the infiniti screen or the I AGREE screen?

I had it stuck on the I agree screen for a while back on my 05. Talked to the dealership about it and they told me a firmware upgrade and navigation update MIGHT fix it at that time they wanted $310 installed for the update disc and they would update it for me. I think they were just trying to sell me stuff. Either way i bought it and well i haven't had that issue anymore, but i've used it less and less now since my android phone has better options, like street view.

they also told me the DVD-ROM drive might be going out, its just like a computer drive. but its been on and constantly spinning since 2003

 

same thing happens to mine when my car is parked under the sun for too long. Stock navi sux pretty badly. I wish i would have found a car without it lol.

 

Ya its not the best but I have it so i'd like to be able to use it! There has to be a fix for it out there...Somebody has to know something (Wrathernaut, Gilley I'm looking your way lol)

 

You try taking it apart yet and taking a look at the wiring..etc?

 

stock navi sucks, i like it because i use it as a light at night and mainly for how much miles i have before i really need to fill up.

 

Hey so Ive been having the same problem. Did A LOT of homework on it including researching the infamous TSB on the unit.

No you dont have to spend that much, nor do you have to go out and do a double din replacement (which would run into the 1k range after you get the dual climate control adapter, steering wheel adapter, and the actual unit)

When the screen pops up, the upper limit is determined by the number of revolutions of the motor, not the actual position of the screen. Over time, this limit seems to go out of adjustment.
To "trick" the limit, while the screen is moving up, quickly press down or tap on the screen so it momentarily moves downward then resumes raising as soon as you let go of it. When done correctly, the screen should raise fully; if you hold it too long, the screen will retract.

Now I dont know how long this will fix it, but mines been out of commission for months. Seems to work when its cold not when its hot, and now finally this year not at all. Did the fix mentioned above and ALL GOOD!

Falling in love with my g35 all over again

(NOTE: I'm going to post this in as many locations as possible since its been years since I've been looking for a fix.)

Thanks!

 

My 03 had the same problem. I traced the problem back to the DVD player for the nav unit. There is some chip or resistor that is loose inside. I ended up jus buy a used nav unit from the wreckers. It cost 150 but now my nav works. It was out for about 2 years. if you want to make sure its the DVD unit. take it out and put it on the vent inside the house for a while. Then jus plug it in and see if it works. You can also warm it up with a hair dryer.

Let me know if you need any more help.
