I am looking for a GPS receiver that plugs into a DB9 port. I don't need any other options, so I am looking for an inexpensive solution. Any suggestions?
I have an old Garmin III+ that I've had for years. It has a port on the back for + & - voltage and two other pins for serial communications. It actually came with a 9 pin serial cable to download maps. They are almost bulletproof if you can find one.
