I need a GPS that was a HARDWARE NMEA-0183 interface to put into my car so I can run APRS (Automatic Position Reporting System). The books say MOST of the GPSes made have this feature, but it is such an obscure thing that none of the GPSes I've looked at mention it at all (on the box or on the website), and I can't really open up the boxes to read the manual. Some of them mention they use the NMEA-0183 protocol, but then say they transmit the protocal over Bluetooth or USB. I need a GPS that has the NMEA-0183 hardware interface using a serial port. I know I can get a cheap Garmin eTrex (about $99) that has it, but I'd really like to get one of the newer automotive-style GPSes that are on sale everywhere. Anyone know of a website that lists which GPSes have NMEA-0183 serial ports or which of the newer automotive-style GPSes have it?

you may want to reconsider the serial port requirement.....serial ports will no longer be supported starting with Vista!

USB-driven serial ports will always be supported (though not by Microsoft) by the software writers who need them.

There aren't any special tricks to implementing a non-real-time serial port through a USB dongle, and near real time interrupt service can be provided with a few 'stunts' in software.

Virtually ALL GPS units sold for "naval" use handle this, as well as virtually all Garmins do too.

Sure they will - just not RS232. USB is still serial - - - - -

I think I'll be staying at W2K and Linux. Vista sounds like a DRM monster.

I might try Vista in 2010. I SURE AS S*IT don't want a v1.0 of that one! Then again, by 2010, humans might come with built-in Vista 3.3 if Big Brother has his way with us.
