(I tried to post this last night, but it doesn't seem to have made it.
I'm reposting it. If it shows up twice, I apologize.)

Wow, it's been a few years since I dwelt in the hallowed halls of
r.a.m.j+wif. Be kind if I'm retreading on some familkaiar territory. I
spent a couple of hours in google's newsgroup search trying to find any
prior threads dealing with this topic and could find nothing. So I ask
for your input.

I have a 99 Grand Cherokee. I asked on this list 3 or 4 years ago about
what was then called a RF Distance Detector, which warned the driver if
something was behind the vehicle as he/she backed up. Brookstone had
previously listed one, but then pulled it for some reason. It didn't
seem like anything else was available at that time.

Well, I've been living in a cave Jeep-wise for the past couple of
years. I just discovered that there is a factory unit that was made for
the 2003 or 2004 Grand Cherokee. (now called a Reverse Sensor).

I'm told this can be installed on any 1999 or nrewer GC.

I'm lookng for some information on how well this unit works and how it
operates *inside the vehicle* (I assume it has an audible warning; Does
it get louder or faster as you backup closer to an object?). In effect,
is it worth the $299 MSRP?

Any comments, or pointers, to a source of information would be
appreciated.

Thanks,

Bob
