Here is an add-on display for the Paktrakr. It runs on a dash mounted GPS system but the app can also run on any Windows Mobile 5 or 6 phone or pda. I'm just getting this finished up so contact me if you are interested in helping test the bits. I'm not planning on charging for the "basic" version.

Note: The backend to the system is flexible and could be modified to talk to any EV system.
