I need to complain.

I have an '07 Avalanche with NAV. I have previously owned several Garmin Nav units, and a built in Nav unit in an '02 Land Cruiser.

I must say that the programming for the GM Nav unit is AWFUL.

One of my major complaints centers around the display DURING navigation to a destination. There are so many various information windows that the map itself is rendered too small for use! When on an interstate, the window for the upcoming exits takes up HALF the dern screen! On top of that, it does not inform you how long you have to go before you need to exit the interstate... only the next upcoming three exits. To compoud the frustration, they chose white fonts on a blue background...not very readable. And try panning around when trying to locate a destination... the info windows get painfully in the way of the map.

Secondly, what if you want to actually display the lat/long of your current position. Can't do it. You can ENTER a lat/long to go to, but you can't display the current position of your vehicle.   You can save it as a POI, but you still can't see the lat/long.   Extremely frustrating.

Here's another complaint.. when you zoom out far enough to see what is going on with your situation, the secondary roads DISAPPEAR! I guess some guru thought this would be safer or something, but it is a stupid idea. When you zoom in close enough to see secondary roads, you can't see the bigger picture.

OK..here's another one. When the system calculates your navigation route, it ignores many secondary roads that are perfectly fine to get to a destination.   Why is this..even when I choose the shortest route? The road is on the map, but the software chooses not to use it!

Also...why are the maps so "cryptic"? They look like some kind of stick drawings done by a 1st grader.   I just think in general the maps look pretty cheesy, even when compared to a 400 dollar Garmin unit!

I really like the backup camera function, very nice for hooking up trailers. I'm sort of wishing I had opted for an aftermaket nav though.

Sorry to complain so much, but I'm really disapppointed in my GM NAV system. Is there any way to get a better DVD and/or replace the programming with better software?

Why do you think there are so many of these units for sale on ebay? People are removing them and installing aftermarket units that are years ahead of GM nav units.
