- Afternoon Scott, I received my OT2 and parts the other day (in a
order from VE6SBS) thank you, I guess I have to get James his unit
A quick question, I've allready dissassembled my nuvi350 and the
mount (easier than I thought) in plans to enable it to be a single
usb connection/garmin serial connection via the mounts connector,
hopefully I'll get to that this weekend and have pics and info up
soon. One thing I wanted to incorporate into my install was a PTT
inhibit switch, to kill the beaconing if I want to tune elsewhere on
my radio's vhf band. I was going to use a transisitor on the PTT out
to my radio switched from a switch mounted at the nuvi to kill it
when pulled low, but then I ran across this:

beaconing and power up/down the nuvi via a 5V reg, otherwise I'de use
the jumper input to get a PTT inhibit, but from what you posted, will
taking PTT_Input low also inhibit the PPT_Output?
Thanks in advance.

the PTT input.
