I would like to upgrade the factory nav radio in my 07public aspen with a mygig nav radio. Mostly for the bluetooth audio streaming and the touch screen interface. What type of my gig do I need (high speed or low speed) and what type of lockpic?

The mygig radio uses a low speed bus in the Aspen, but was only offered for the 08-09 model years. I'm not sure if you'd have any issues with the 07 install.

The lockpick you need to choose is simply the mygig type. You change the bus setting with jumpers at time of install. There are instructions on their website that go over this in detail: http://www.coastaletech.com/media/MY...NSTRUCTION.pdf

Here's a nice site with detail on bus speeds for various model years of Chrysler vehicles: Jeep Grand Cherokee WK - MyGIG Multimedia Infotainment System radios
