You should not have been able to connect the two cables using a male-to-male. The Garmin cable should plug directly into the BWZG1844001 cable.
The BWZG1844001 is now included with the BC-GPSK (as of about 2 months ago).
Auto Locate does not use GPS. It scans until it finds a Motorola or P25 control channel, then uses the information contained in the data stream to identify the site, then looks up the location.
OK, now you have confused me. I have a GPS hooked up and working, and when I was driving I hit "autolocate" and it did come up with the area.
So how exactly do I use the HP with GPS? Do i just enable it and it finds the right database for me on the fly?
