Hi, I am trying to get my MDA Compact & SPV M500 to recognise my Bluetooth GPS Unit I bought recently The Unit is A Copilot BT-GPS-365E50. My problem is, I installed Mobile Bluetooth Tools and it installed with no problems. It recognises my GPS Unit, but when pairing the devices the com port setup screen flashes for a moment then disappears. I therefore cannot setup a BT Serial Port. Any suggestions? Is it the GPS Unit? Is it not compatible with my MDA. I have tried this on both my Phones and get the same result. They are both HTC Magicians. I used this process on an XDA II with no problems. I just want to get my SatNav up and running. Hope myou can help and thanks for reading..
