The sparkfun venus is a pin-match for it (gnd- tx-rx-3.3v on 0.1
centers - tx to rx, rx to tx), so as long as it wasn't a console or
otherwise used it could work.  http://www.sparkfun.com/products/11058

The GPS antenna is at the end of a short or long wire, the mag mount
is about 10 feet or more so wouldn't be near the wifi.  I have had
problems with wifi interfering with GPS if it was "right on the case".
