this thing works great! fast satellite pick up, fast calculation/recalculation. bluetooth is nice to have, able to pick up contacts, etc. from my nokia6133. although its a bit buggy with the txt msg download (at least with my phone). the unit automatically picks up & recognize new incoming msg, but when i click 'review', it hangs. other than that, this unit is great. although i haven't used the mp3 player functionality/european maps.
