resistor and capacitor included in it? The PTT line could be tied into
the audio line in the cable rather than using the internal jumper. If
this is the case, then the assumption that the HT jumper is magically
being enabled is untrue.
> I'm able to change the commands on my tracker2 via my nuvi 350 duh.Your posts do not make it clear as to what it is that you are changing
on the OT2. You state that you can change settings, and it can be
inferred that these changes being made somehow fix the issue at hand.
Of course the reverse could be true, and that you are just adding in
superfluous information as a red herring to throw people off track.

but you can not assume that the HT jumper is enabled without knowing
more about the cables you are using.

repair components, but rather identify an issue, find a cause, and
then from there implement a solution.

there may be an intermittent issue somewhere in the mix, and we are
attempting to help you identify where the intermittent issue might be
located. To do that, we need to know what you have, what you are
doing, and what the symptoms are. Partial information, mixed up
results, and unrelated information provided just makes it that much
more difficult to help you.

problem as well, but that's not really a good solution, is it? As for
that being the only problem, I don't think so. Have you determined why
you weren't able to get messaging working? I sent a message that you
obviously received, and replied to. Have you gotten messaging working?
Looks like a lot of attempts from you to send messages to N7HRI, but

control, but that does not mean that every unit has the exact same
issue. If I ran mine over with my truck, and said that the board was
cracked, would you automatically assume that your board is cracked as

it. Best case scenario, he finds some solder bridges, or long
component leads that are shorting out on you. The other option is that
he checks it all out and finds no issues. He sends it back to you, and
now we are right back where we are now.
Systematic experimentation now might save you the time and expense of
sending a perfectly good unit back to Scott.
There are a lot of little twiddly bits to deal with, and niggly little
details that can cause issues. When everything is working, everyone is
happy. When things don't work, it can be annoying, but you can usually
find the problem and rectify it. However, when the issue is
intermittent, it can drive you batty trying to find the cause and
We're just working on finding the cause before we all go batty! 8)
