Is it cost prohibitive? Is it a simple chip/software? Just curious.

Someone asked this a while ago, and if I remember right it's a PITA...

I have the '09 Command and used to have the '07. There is really not a huge difference between the two, after all, most people either listen to satellite radio or play their IPOD. This change out cost, time, etc. is not at all worth the benefit my $.02. The Navi while somewhat upgraded is essentially the same in both 09 and 07.
