1) Havent a clue, but I'm shure a electronics/computer whiz could knock one up
2) Tomtom for the route planner, ChekPOInt + a camers database (available from www.pocketgps.co.uk) have the advantage of being free.
3) Do a search for PDA or Tomtom - lots of solutions out there, all with their own pluses & minuses for the MINI
I'll second Tom Tom as good navigation on a PDA and checkpoint works as well as
most and is free. To add laser you really need to add a seperate radar/laser dectector,
I don't recall seeing a laser only unit except for the illegal in the UK laser jammers. If
you go to www.newministuff.co.uk they have various ways to mount the PDA.
