Anyone else having problems with theirs?

I just got a Chevy Avalanche about 6 weeks ago and I love the truck! But the only thing that sucks on it is the navigation. It keeps "blacking out" for lack of a better term. The truck position on the map will get stuck in one spot.

I have been on the truck forums and have gotten some advise on how to fix it. Various ways to reset the software and what not. I was able to recover it a few times but now its been out for days and I can't get it working again.

I know there are a lot of GM truck owners here, thought I might see if anyone had a solution.

Before you say "take it to the dealer" I have been told by a few people that this is a known problem and all they do is the same reset I have done. They won't replace the head unit under warranty because its an "intermittent problem".

Nevermind, I think I found the problem. It looks like it was a setting in the Gen 6 lock pick that was conflicting with the GPS.

Have one in the Denali and it sucks bad. It's not very user friendly!

Which setting was it in the lockpick?

My mom has an Escalade with a lockpick and kept having similar problems. We finally traced it down to when the lockpick was being used. I'm not sure if yours is the same but on hers you actually have to turn it on to access all the features, it doesn't just automatically come on when the ignition or navigation system come on.. She's still having problems, so now she leaves the lockpick off unless she needs to input an address on the go or has a passenger who wants to watch a DVD in motion.

It was the "OVERRIDE MODE 1 and 2" while having the DVD in motion on. I switched it to override mode 4 and shut off the DVD in motion and the GPS instantly found itself on the map.

The DVD in motion is supposed to default back to off once you shut the truck off but for some reason I don't think it was.

It all made sense because the problem always seemed to happen after letting my son watch a DVD.

I find mine pretty easy to use and indeed helpful. But for shit sakes they could at least update their maps. The maps are missing roads that were built 10-20 years ago. FWIW, I have the 1st version of the GM/Bose nav system in my wifes 2005 suburban and the maps in my 2008 GMC truck are the same as hers. No updates whatsoever.

i've had very similar issue and deduced the issue to my gen 5 lockpick.
i now just go into the settings (mute 3-4 times) and select or de-select the nav override and usually all is well and nav is back to tracking as it should be.
no blacking out, but just issue of long delayed gps info such as vehicle heading and location on the map.

There is a new map disk available. There is a guy on ebay that has brand new genuine GM map disks for around $160 bucks.

This makes me think real hard about just buying without Nav. and keeping my portable Garmin.

the only feature i really like about my GM OEM Dvd nav is the factory back up camera. It works very well and excellent picture in virtually any condition (rain, night, day).

I've had Pioneer dvd navs and much prefer these and the aftermarket dvd navs as i think overall they are a better product and usually minimal to upkeep/refresh the nav data; definitely not $160 to buy the latest disk to upload.

I'd like to have an iPad2 custom installed on my vehicle that is capable of Dvd, nav, movies in HD, etc, etc, etc as skies the limit with that.

While I like the size in my factory nav in my Yukon, the smaller one in my Toyota Tacoma mirror actually have better depth perception.

:nono: I would think twice about getting a GM vehicle with Navigation. And I wouldn't pay for their "new maps" disc just yet.

My parents just bought a 2011 Buick, paid the extra $2500 for the Nav feature. They came down for a visit, and their Nav system didn't even have my street in its maps!! (and it was built in 2005-2006!) While their little Garmin $200 GPS, of course showed my street. Man was he mad... :mad:

By comparison, my 2010 F150 with Nav, has my street and many newer roads in my area...

No wonder GM was almost bankrupt about 2 years ago, and we had to bail them out!

Doesn't GM now have just the back-up camera with the pic in the rearview mirror, and no Nav. as an option?

My truck came with the Bose nav/DVD but no back up cam. I installed my own cam in the factory location and I bought the OEM mirror with the video screen. It works and looks perfect.

Just make sure to get a truck with integrated Bluetooth for hands free phone. Sooooooo nice :thumbsup:
