Hi all, my 08 H3 comes with an OEM nav system. The unit is good considering the singal. While the nav disc seems not perfect, especially the POI. For instance, less than 100 costco stores listed while there are at least 8 locally! I'm wondering whether you guys have tried the most recent NAV disc, does it have a plentiful database and worth the $199?

 

I too, am on the fence about getting this new 2011- $200 disc.
The older version I have is actually quite good. It has great contrast and shows lots of important street names at a readable size at the larger magnifications.
I have used it for many purposes and the current disc even shows National Forest roads in the National Forest areas and BLM. That is critical for off road driving
If you do get this newer disc, report back if you are happier

 

For $60 I put TomTom on my iphone and bought a window mount....much safer and has many more options. GM Price $199

 

Shale, I sent you a PM with my opinions

 

I have the 2009 Ver. 7.3 Nav Disc I am selling for 55$ shipped. Ill be posting a promo up on the site this weekend, but the first 5 people to order the 7.3, When I get the 2011 ill give it to you free. You can email me at Hummer@hummerworks.com or send me a PM on here either way.

 

Call this # 877-628-3472,it is the GM navdisk order line. Be nice and tell them when you bought your H3 the dealer told you you would get 2 free disk upgrades for free. They will ask for your VIN # and should send you a 2011 disk.

 

If memory serves me right I believe they stopped that program for free updates in 2009.

 

I called the number today....only works with 2006 & 2007....was worth a try

 

Aha, I have an 2007, they sent me a new disk in Feb. Perhaps this info. will help someone else.

 

I have a 2008 H3, and would like to upgrade the Nav software. I see the posts above seem to be old posts. Anyone have ideas for upgrading to new software?
