Okay, I had a 2005 version 4.1 in a 2006 EXT that was working. I ordered an upgrade from the GM center that got here today. It is a 2006 version 1.0. I was told when ordering that they go by part number now. The PN on this new one is 15906573U. When I put it, it gave me an error message that said "No CD". Left it in for 10 minutes as instructed. Pulled it out and reinserted and map, etc came up as it should. Haven't tried it going down the road yet. Did I get the wrong version for a 2006 EXT?

Just in case anyone's interested, new map DVD worked for one day then started getting "No CD" message even after reinserting it numerous times. After about 10 times it would read it for a little while then quit. Called Nav center and they told me to try old disc - it worked fine. They also told me to clean new disc and look for scratches. I found numerous scratches a brand new disc. Will return new disc and wait for new update in mid June.
