walked off the lot with my 2005 FX 35 today and like it. The rep took an updated Nav disc (I believe 6.6 or something and definitely an 07' upgrade disc); but it didn't work. So I had to temprorarily use the 2004 upgrade disc that came with the car.
Should I just go to Infinity Dealer and ask them the deal? I live in suburban Chicago, lot's of new highways and roads/and travel the tri-state area.
Thoughts? I am obviously trying to not have to buy some $80 upgrade.
