</span>Argent Data Systems has a puck style GPS receiver with RS232 that<br>
requires a regulated +5V supply.<br>
<br>
The Garmin GPS18 series is still around, sounds like you probably want<br>
the GPS18PC (DE9 connector and a cigarette lighter plug last time I<br>
bought one).<br>
<br>
Good luck with a compass, and please report back if you find one for<br>
cheap. Most GPS units will report heading, but unless you're moving<br>
at sufficient speed it's garbage. Some continue to report the last<br>
heading they had confidence in, others simply report 0 when they're<br>
unsure.<br>
