Welcome to the group and to APRS! > I have a Garmin Nuvi 350, OT1+ in case, Garmin FMI cable, and > an Alinco DR-112, and a 4-way power pole splitter. That won't work. Keep the FMI cable to use with the Nuvi for when you get a T2 (Tracker 2... OT2m, T2-135, T2-301 etc.) and get a GTRANS cable to use with the OT1+. The Nuvi must be powered from the cradle (rear connector) unless you have done some re-wiring. > I know there has to be a cable between the DR-112 and the OT1+ > to handle the audio coming from the ext speaker jack, and the data > being sent connected to the 8 pin mic jack on the front.

I'm not familiar with the radio, but the cable will carry the transmit and receive audio and PTT. I don't know if power is available on the mic connector or not. If it is, typically it might be able to supply enough current to power the OT1+ but not a GPS receiver. Do you have the manual? See above... the Nuvi must be powered externally... i.e. via the cradle, but you need a GTRANS cable (for now) and not the FMI cable. The radio obviously needs power. The GPS needs power. The OT1+ needs power. Draw it out on paper and decide how you will put it all together. The GTRANS cable (or the FMI cable if you decide to get a T2) gets power from the connector on the right side of the Nuvi. 73 es cul - Keith VE7GDH -- "I may be lost, but I know exactly where I am!"
