I found a work-around solution to this after much searching. Windows marks COM ports as used once they are allocated. Bluetooth Devices keeps incrementing the COM ports when you re-pair the GPS because it thinks the old COM ports are in use. You need to go into regedit and change the value of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\COM Name Arbiter\ComDB - you can find details at http://www.ftdichip.com/Support/Document...gistry.pdf - every COM port has a bit in the ComDB value that is set to 0 if it's available or 1 if it is not. So you need to change the 1's to 0's and then you will once again be able to assign the lower COM ports.
