If it's the same one that's pictured. It's Serial and PS/2. The PS/2 port is only for the power so you could use a USB to PS/2 adaptor for the power or rig a power setup from your PSU. I have this very one and it also works with the Street atlas software.Originally posted by m3rdpwr
Does anyone here know if it's USB, Serial, Battery powered, other power requirements? Also, is it NMEA 2 compliant.
