Cheap gps to link to vhf??

[JIM_TEAL]

Stupid loss of Garmin 72 leaves me with no regular position input to Vhf. Any reccomendations for a cheap gps dongle which can output nema to go to the radio will be welcome. Does such a cheap solution exist or do I have to buy a gps set with Outputs?
Thanks in advance

GlobalSat BR-355 from EBay, £25. You will need to cut the connector off and supply it with 5V, but that's only another £1 from Ebay if you use a car socket USB power thingummy.

Is that a serial one or USB? USB no good in this application.

Excuse my ignorance but how do you do that?

Thanks Angus and Fantasie.
I'm not very sure about electronic connections so please bear with what may seem a stupid query. On the e-bay site there is no spec showing output etc or wiring diagram.
Does it output the NEMA format and which wires are which if I cut off the plug, as suggested, to connect to the radio?
Regards

Here is the full Specification

Pinout...

It zips out NMEA on the Tx pin. I have one talking to my VHF.

Pin 1 to your 5V supply ground and your radio NMEA- in.
Pin 2 to your 5V supply +.
Pin 5 to your radio NMEA+ in.

I use something like this to get 5V from 12V. I ripped the guts out and mounted it in a small box from Maplin for 30p.

May I thank Angus for the suggestion, I had some problems with my fixed GPS feeding both the Seatalk network and the DSC Radio, I used the setup above for the DSC Radio and it worked perfectly.

FWIW, I used a 7805 component to get the 5v input to the GPS: 12v to the left leg, NMEA ground to the central leg, red wire of the GPS to the right 7805 leg
