15619T3-mini to nuvi 350
- Jun 1, 2013I've just received my T3-mini and loving the form factor...I'm looking
forward to getting this working in a tictac container.
I am using a Baofeng UV-5s and the interface to the radio is working, I
can transmit and it shows up on APRS.fi using a fixed location. I am
now trying to connect the NUVI 350 using the garmin minib to serial
pigtail cable. The gps cable pinout is yelow - data out, white data in
and black ground.
I have done the soldering to connect it this way
yelllow to A_RX, white to A_TX, black to GND
and also this way
yelllow to B_RX, white to B_TX, black to GND
In each case I set the Serial interface A or B to Garmin but it won't
kick the NUVI into Fleet managment interface (FMI) mode and does not
receive the gps data. I am thinking there is some key instruction
missing to connect the ground to a different point where there is
Thanks for your help.
