BN,
My Mio unfortunately did not come with the "Co-Pilot" software. I recieved "Medion Navigator" software with European maps, which to be honest I never really use. It does the job ok (clear, loud speech, very readable and good street data) and pretty accurately, but I was only looking for a reasonably accurate GPS reciever to use with Pocket FMS. The reciever itself is built into the back and flips up, with a connector for an optional antenna.
There seem to be rather a lot of Mio 168 clones doing the rounds; There was the OEM Mitac version, with "Mio Map" software, and the Medion version I have. All versions seem to have the same windscreen suction mount, car adaptor, bike mount, power cable and screen covers. Mines came with a dock instead of just a sync cable, I'm not sure about the other ones.
If you're looking for one preloaded with CoPilot, try
this one from Evesham. It was a lot more expensive than mine however, but from reviews I've seen, the CoPilot software should be worth it.
