Hi Phil, That is the picture and I made my cable. I am using a Garmin GPS V not the Nuvi 350. But that is not anything to worry/wonder about too much. Both receivers talk the same protocol known as the Garmin Protocol. The Nuvi has the added feature of FMI which rides on the Garmin Protocol. If you were to follow my path somewhat, you would need a cable to connect the Nuvi350 to the OT2m. That keeps the OT2/GPS connection easy. I ordered a Kenwood version of the GTRANS. I didn't have any right angle 2.5mm connectors at the time whereas I have a ton of DE-9 connectors. The right angle Kenwood and USB cable are sitting in the project box. If you buy the Kenwood version, you can use it, just remember the tip and ring need to be swapped. There are two reasons I followed this path. First, I wanted to use the Garmin Protocol for communication with the GPS. By doing so, I get an antenna for a repeater object, a car for a vehicle, etc. In NMEA mode, I get dots. So, a dot or an antenna, car, etc? I chose the cool icons! Second, I wanted less clutter. With the GTRANS inside the OT2 it sees no strain or stress of the cables. You could certainly splice the GTRANS in anywhere you like. My OT2 has five connectors on the back. One is for the LCD which exits the grommeted hole. One is for the radio and the other three are in a three headed beast (rather than the two headed version Scott sells) that provides a PC (Port A), GPS (Garmin Protocol/Port B) and GPS (NEMA/Port C, Pin 1) connection. Port C is my addition! I would bet your IC-91AD uses NMEA only. That makes it easy. There is also no need for more than that. The radios do not send waypoints to the GPS anyway. Of course my assumption is based on the radio I have, the IC-U82 (UHF only) and my friends radio, the ID-800 (VHF/UHF). Okay, inquiring minds have to know: A total 5 sentences, RMC, GGA, GLL, GSA and VTG are available according to the manual (page 58). More manual information (page 34): The IC-91A*/91AD can be operated in digital voice mode and low-speed data operation for both transmit and receive. It can also be connected to a GPS receiver (compatible with an RS-232 output/NMEA format/4800 bps) and transmit/receive position data. Best regards, Fred
