4.2.1 Garmin GPS18PC
The GPS18PC is a GPS module receiver that interfaces via a 9-pin D-SUB RS-232C serial port.
Refer to the wiring example using an accessory cable (2.5mm 3-conductor plug) that comes with
the TM-D710A/E. Power is sourced from the 12VDC supplied from a vehicle cigarette lighter
socket. Because there is no screen, you cannot use the Waypoint function.
