So I've managed to downgrade the ipod touch 3g to 3.1.2 then did the jailbreak for it. Installed GPSSerial 1.3 and downloaded TOMTOM 1.3. For some reason TomTom doesn't see the gps receiver and keeps asking to connect to gps. Is there something I missed? This receiver works fine with my ipod touch 1g, so that's not the problem.
