Inexpensive GPS with NMEA 0183

[capngwyn]

Hi,

I need an inexpensive GPS unit that outputs NMEA 0183 data.

I have a VHF radio that accepts NMEA 0183 as input, but my chartplotter does not output NMEA data. I feel there should be the equivalent of the numerous USB and Bluetooth units but that outputs NMEA data instead.

Any suggestions?

most Garmin handheld GPSs (e.g. for walking / hiking) output NMEA usually as serial RS232 data, this includes the first Etrex units like this one :-

The price is certainly right. Do you know what kind of cable I would need?

Yes on the back of the Etrex there are 4 gold 'pads', here is a picture of my Etrex and connector, I got this 4 way connector from pfranc.com but I'm not sure they are still around, the other end of the cable is a female 9 way 'D' connector, I have also seen pictures of versions where the cable has the 4 way plug on one end and a serial (RS232) to USB converter + USB plug on the other end
