Anybody have any idea if the Wintec WBT-201

will work with Tom Tom Nav 6 and my 700p?

I emailed the manufacturer, and the response I got was in comically broken english. Not much help. The cool features of this unit involve data logging, ie the ability to log a trip and then paste the data on Google Earth maps, satelite images etc.

The above link shows the output "Output Message : NMEA 0183 (GPRMC, GPGGA, GPGSA, GPGSV)"

The globalsat bt-338 reports out as "Output format: GGA(1sec), GSA(5sec), GSV(5sec), RMC(1sec),VTG(1sec)"

These look pretty similar, but I don't really know what I'm looking at.

Any ideas?
