Hi

Not a big expert on this but some basic checks
Are you using a straight jumper or a 10K resistor. You only need to flash it to start the data. Different jumper values give different data packets.
The other thing to check is if your using a cable is weather the RS232 box is checked. Usually not for blue tooth, but for cable. this can stop data trans mission.
The best way to set this is open the ADX file in tuner pro and check/uncheck the rs232 box.
