Nav goes up and down, won't stay up
 

Since I have had my car the Navigation has not worked properly.
If you push the button it will pop up and then go back down.

If you try a couple time, by pushing the button and then holding the unit with your hand, slowing it's rise and then let go just before it gets to the top it will stay up and work properly.

I took it apart yesterday and greased all the lift parts and looked for anything keeping it from extending fully and found nothing.

It almost seems that the electric motor is too weak.

Has anyone found a fix for this?

Does anyone have any spare parts from a broken one?

If your under warranty still take it to the dealer. They have a TSB for it. Basically replacing the motor unit.

Nope 05' with 118k on the clock

This thing is really annoying.... Sometimes it will stay up, but most of the time it comes up and then down.

Just pull the nav forward when going up and it will stay up. I have an 05, same thing, just don't us the tilt and it will work fine.. Keep it tilted forward...

I'll try that again. I did that before and it didn't work. but I will give it another shot.

You may have to help it get up the first time by pulling it up while it's going up, then it should be fine. (Don't wait til it gets to the stopping point, pull on it the second it starts coming out) Ok that sounds G A Y but what your explaining is the exact same problem with mine a year ago.. and remember to keep it tilted forward the whole time your doing this. Good Luck Champ!

Cool, I'll give it a try at lunch...
Thanks for the advice.

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!

Anybody have a link to the TSB? I searched first, but didn't find it.

The car I'm looking at right now is having this issue and I'd like to know approximate repair costs before I start negotiating a price.

I ended up finding it on the web.
