I have a One XL I got about 2 weeks ago. When I first got it, it would have my location almost right on all the time. Now after adding lots of POIs and a few applications it is acting "slow". It shows my location behind me, sometimes as much as a block or more. As I drive, the screen jumps from one location to the next instead of a smoother "tracing" transition. The voice is still right on and tells me to turn at the right time, but the map seems delayed. I thought it must be because I was filling up the memory. So, I got a 2gb card and copied everything to it then deleted everything on the internal memory. It is still running the same. The menus seem to go a little faster, but the map still shows my location behind where I really am (unless I am stopped). Any ideas how I can keep all my added things and still have the speed I had in the beginning?
