Has anyone developed a program that can be run on the hard-drive based navi unit in the 99 TL? I've seen the posts that allow you to transfer maps of different regions onto the drive, but I'm looking to see what other purposes the unit might serve. Also, I've been searching everywhere to find the specs of the unit. Alpine's site is no help at all. I'm looking for the processor type and speed, RAM size, etc. Can anyone be of any help?
