There was a website called GPSunderground, that had a bunch of good tips for modding win CE6.0 units. Its also where i got the info to get the newest gps maps up and running. So far ive been driving the benz for the past week, and been tinkering with the unit. So far soo good, the gps is fast and responsive and overall menu navigation is pretty straight foward, my only little itsy bitsy beef with it so far is that if you turn the car off for more then a few minutes, when you turn it back on, it needs to reload the gps software each time you select navi.. just a small delay i will have to live with. I would say it would be the same as waiting for a portable gps to boot when you turn it on. Once its loaded up, you can switch back and forth beween navi, radio, ipod, bluetooth; instantly.

I dont know if the processor is different beween the G1311, and G2104, i hope yours will be as fast as mine. Thats the one thing i hate the most is laggy interface on special electronics such as this.
