Is/rx Gps Nmea Serial Data?

Hi All,

Just curious as to whether or not it is possible to find a "tap point" in the system to take the NMEA-0183 data from the GPS receiver on the IS and RX models, and if so where would be the most readily accessible tap-point. I ask this because as a licensed amateur radio operator, I have APRS (Automatic Position Reporting System) installed using a Kenwood TM-D700 VHF/UHF mobile tranceiver. I currently receive the GPS data from a handheld Garmin eTrex in a small cradle on the dashboard of the IS200.

There is a risk that this arrangement will not work that well in the RX400h because of the rain detector mesh and heated windscreen elements which, from what I have been told, have a tendency to sheild out the GPS satellite signals.

It would be useful if I could find a tap-point in the vehicle's own GPS receiver which I can then feed into the Kenwood for APRS. (Only needs to receive the NMEA serial data, doesn't need 2-way communication).

Alternatively, if Tracker Horizon is installed, is it possible to get an NMEA feed off its GPS receiver?

Thanks in advance,

Leland
