What would you chose? Money isn't a huge issue. Definitely needs to be double din, have navigation, touchscreen, and bluetooth. I have a friend(with money) that wants a badass nav system. It'll be going in a cadillac limo.

 

JVC New stuff is great. The 30 is the way to go imo. Only problem is the usb in the front. Some people may like that.

 

I have had really great luck with the pioneer avic series and eclipse nav units in my trucks and in customer vehicles.

 

pioneer z3 best double din out there navi hard drive i got the 2008 model and its badass 30g memory the 2010 is way betterrr tho

 

I have an avic unit in my truck and it is great. Very reliable and works flawlessly.
