Greetings, I have a 2005 Magnum and tried to update the program on my GPS. It was working fine, just 10 years out of date for the roads around here. I bought an update disk (04064033AL) and installed it. It seemed to install ok but when I tried to use the GPS it said unable to read the CD ROM, or words to that affect. I put the original disk back in and it says that that disk is older version of program than what is installed (DUH). I called the seller of the update disk and he sent me a new one immediately. Same problem. He then sent me a third one that he tested before he sent it and it does the same thing. I now have four gps disks and no operating GPS. I tried disconnecting my main car battery to reset it but no joy. Anybody have any suggestions?
Thanks,

where are you buying the update disc from?

this is the fca site:
http://chryslergroup.navigation.com/...ChryslerNA/USD


their part number is different.

 

I bought it off ebay. I went to the site that you posted and if you zoom in on the disk picture they show it is the same number as mine. The disk is identical to the three that I have.
Thanks for the reply.

Sounds like a candidate for a MyGig RER or 730n upgrade/retrofit.
