Hi All, This is my first post so hope it's in the right place. I recently bought a 2nd hand navman (mio 168) with tom tom 6 installed, worked great, bit of a weak reception from built in antenna but I used it in car with external antenna so it was grand. last night installed "gps monitor" (winfast navigator/ce monitor), played about with some settings nmea/sirf etc, etc. now I can't get it to receive anything on either tomtom6 or gps monitor. done a hard reset this morning and reinstalled software to no avail, still no signal, development view after a long while gave some lines of garbled characters/symbols - have I destroyed my beloved mio 168???? Please help!
