I was heading out on a weekend trip recently and had  a problem with
the audiovox CCS-100 I installed several months ago.  It didn't work
at all, but it's "on" light was coming on when I turned the unit
on.  I stopped and decided to try to troubleshoot it before it got
totally dark.  I really didn't want to drive 3 hours on Friday night
with no CC.  It passed all the tests in the audiovox manual.  they
seemed to test all the connections and wiring but not the actual
unit.  I got back on the road and it still didn't work.  I resigned
myself to having no CC on this trip.  The manual for the CC says that
you should turn it on and wait a few seconds before engaging it.  I
remembered that I rushed that process, hitting set right after
turning it on.  So I decided to give the unit a couple more power
cycles as I drove on.  sure enough, after about 10 minutes I felt the
gas pedal fall out from under my foot as the unit took over on an
uphill section.  The unit worked flawlessly for the rest of the
trip.  So maybe it just got really upset by my rushing it to engage
so quickly after turning it on, and needed some time to recover from
that?  anybody else seen this kind of symptom?  I just would like to
know if it isn't going to be reliable for me.
