[aprssig] Nuvi 350 - D710 error message

[Sam Guccione]

I updated by nuvi maps and updated the D710 yesterday. Attached numi to D710
with Argent cable and pressed the BCON button. I got this message "This
accessory is not supported."

I can clear the message by touching OK. The nuvi is sending aprs locations
to the screen ok. 

Not sure if this is telling me my Argent cable is bad or the D710 updates
changed something or my map update changed the nuvi. Anyone experienced this
message? Have never had
It before. Ran the D710-Nuvi for at least one year in the car without
failure.

Thanks, Sam K3BY
