How to install new nav dvd? I purchased the new Nav DVD from the dealer at a pretty high cost of course (gouge). Anyways, I went to install it (Data ver.07.1) and when i put it in my dvd drive it says "Reading drive data" or something along those lines, but nothing ever happens... Is there a trick to install this? How long should I let the dvd read in? Am i missing something here? The dealer said to just put it in and it should be instantaneous? Did I get sent the wrong version? or? I'm upgrading from the stock disc (2005). The updated new part number is 86807-12016. Thanks in advance
