I think for future reference here is my painful configuration experience of COPILOT Version 5 with a Copilot Bluetooth GPS receiver and XDA II.
1.Check that the Quickstart Package is complete:
-GPS receiver User Guide,Ventmount Kit with attachment for PDA,Bluetooth PIN code for GPS receiver.
- User/Installation Guide
- CDs and 128Mbyte SD card
2.Install the Software from the SD Card according to the User Guide
3.Check the Version number and note it down.Go to the Technical Support section of the Copilot Website and see whether there are any Patches available.
3.Deinstall the software from your device and install the patched software which you need to copy onto your SD card.
4.Install the software.
3.Check that you have bonded your Bluetooth GPS receiver with the XDA II and enable Comport 4Inbound and 5 Outbound.(ROM Version 1.60)
5.Use Code 0183 as the Bluetooth device PIN code
6.Go into Copilot software and everything should work as it did for me if you haven't lost the will to live by this time !
7.read this first : Buy a SatNav system with your car and haggle with the salesman like mad (its quicker).
Hope this helps everyone else as people helped me here.
