I have been reading alot of reviews on in-dash GPS/DVD units and this seems to be the most "highly" rated unit out there. Before I spend the $900 I've saved for this mod, I wanted to get maxima owners opinions on these in dash units, particularly the pioneer AZ-2.

• are they easy to use
• How is the GPS w/out satellite (the pioneer uses a hard-drive based system) ?
• Are they worth the money?

I figure since we all own the same car regardless of which ever generation then we may share similar tastes, relatively speaking….Thanks in advance
