I just recently upgraded my MK IV system to V32 and I finally purchased a new Nav DVD, the 2010 High 2 DVD package, but when I insert the DVD I get the following message...

Error in reading map CD/DVD
Please check the CD/DVD

I get this message with either disk1 or disk2. I tried re-installing the V32 firmware, and the DVD drive can see the CD that I burned for that. It starts the upgrade and then quickly tells me that my system is up to date. I have confirmed that the computer shows 4-1/00 on the console. Unfortunately I no longer have a map CD to try with my system.

Any clues?
