RE: V2 serial port?

Sorry for getting your name wrong on my earlier post. We seem to have
similar interests. I just got a link to your post on the Alpine interface
and saw the reference to the FM mod. Now I just have to convince myself that
I want to open up the JBR that I have only had for a day! I think I may dig
through the code a bit more before I dig into the JBR. I have been working
with electronics for over 40 years now but surface mount is not fun to play

Thanks, Travis

Yes, you can do that. The FM (and V2) have 4-pin jacks. Everything is
prepared internally, it's a matter of adding/moving bridges and resistors.
see when looking at the PCB. (Well, for the version I came across.)

The headphone jack can get the serial RX, the line in jack can either be
digital in or digital out. Default is digital in, iirc.
