The subject says it all but here are the nitty-gritty details. OT2m connected to a Garmin Nuvi 350 via one of Scott's Serial Splitters, Port A setup for Garmin (Red cable) and Port B setup for Auto (Blue cable). The cable from the OT2m to nuvi is one of Scott's cables too.
For a radio I have a Motorola with a cable from Jason over at RPC-Electronics to interface with the OT2m. Power comes from that cable as well. The OT2m has everything setup but the Nuvi won't go into the "Dispatch Mode". Ideas, Suggestions, Advice? Regards, -Frank C.
