I am a Mac and probably just not smart enough to get Windows. I am looking at the Pioneer AVIC-U310BT at $599.99. If I understand this thread correctly, I will need Parallels or VMware Fusion at $79.99 and Windows 7 Home for $199.99 for a total of $279.98 to have PC support for the GPS. Other posters are suggesting this solution as though it doesn't increase the cost of their GPS / CD Deck by 47% - am I missing something?
