[TR] RadioMobile hook up question

[Randall]

Sounds like time to contact whoever sold you the unit.  A 1070X did not
originally have a USB input, so what you have is a 1070X case that has been
converted with modern electronics.  The polarity switch may or may not be
functional.  I did a quick Google and found one firm doing the conversion
who say you have to specify polarity up front (presumably meaning the switch
does nothing after the conversion).

Either A1 or any fuse block terminal should do as a source of power.  But I
would want to use one of the 'green' terminals on the fuse block, so the
radio goes off with the ignition switch.  A1 is hot all the time.
