Having communication problems between the T2 and a Nuvi 350. Sporadically I get
"Serial Accessory Requires External Power" and then I lose my call sign on the
nuvi display. Also when trying to sent text ,the out box message status never
changes from sending. Apparently my messages are getting out but no response to
the T2 that it was received so it keeps broadcasting.
The --version command works fine it gets a confirmation and an inbox reply
Im using a serial cable supplied by argent data to connect the T2 to the nuvi.
Also I have checked the voltage from the Garmin power point and it is a
constant 5.172 v
Thanks
