The other day I was using my nav for the 1st time since I got my baby on oct 4th. I used it to see if it would tell me where I was. It showed the circle where my car was but no roads until I got to the main interchange. It did show a red dot but that was to show where the grocery store was. Maybe if I zoomed In it would have shown the actual road. This was the nav on the car not on my iphone.
Hawkeye, I notice that you have an 06. So do I and I found out something very interesting.
Bring up the Planned Route screen and hold your finger on the right lower corner of the screen for about 10 to 20 seconds.
On my NAV system, another panel pops up and if I touch the "RUN" screen button then it puts the system in a more versable mode that allows programming on the fly. If I look to the right upper corner, there is the bottom of another screen button that is really a "RETURN" button that returns you to the "Planned Route" screen.
What this option does is let my passenger program the system while driving down the road which supposedly could only be done on the 04 & 05 model years AND if you don't need the NAV system, the passenger can replace the NAV disc with a movie DVD if they'd like. Just don't let any law enforcement see that in the center of your dash.
The only draw-back to this function is when you stop and turn off the ignition, you have to go back through the procedure again.
My XLR is #165 of the 250 Limited Edition Star Black Matallic 2006 models. My XLR actually was built in Nov. of 2005.
Now, I don't know how many of the 2006 models were really built in 2005 or have the early systems like mine but it only stands to reason that there were 164 2006 Limited Editions models before mine that has the same NAV system that I have.
Also, while on the subject of the NAV Disc themselves, I recently purchased a Plextor DVD/CD Burner from Newegg.com for about $70.00 that will duplicate the disc so I can save my orginals and use the copies. I'll really be testing out the copies next week while driving down to The Texas Mile event in Beeville, TX. The local tests I've made here in the Los Angeles & Orange Counties have been just as good as my orginals which are the 2004 - 2005 and the 2008 - 2009 disc.
The Plextor system is a single disc RW system and the way it works is you'll need a blank 8.5GB DVD disc, a greater that 8.5GB USB memory stick. You put your GM NAV disc in the tray as the source disc, select the Disc copy function of the Plextor unit then insert the USB memory stick into the USB slot and push ENTER and in about an hour after all the data is copied from the disc to the USB memory. The unit will eject the source disc and instruct you to insert a blank DVD to burn for your copy.
Don't even think of trying to use a burn disc smaller or larger than 8.5GB as that is the size of the orginal disc and the Plextor system has a maxium cap. disc of 9GB.
