motorola v60gi and hf car kit

[Kardain]

I own a Cingular v60 and when I hook it up to my hf carkit, the backlight
gives off an irritating feedback (kinda maybe) hum, sorta like a 60 cycle
hum. Only happens when the backlight is on. Not really noticable when
using a conventional headset. Is there a filter I can install inline with
the audio out to eliminate that problem (diy project?)?
b4 neone suggests get a new phone, I would but got bills to pay first.

Was thinking more like solder in the hf unit. Phone's a little outta
warranty. Its all good though... shoulda said the car kit is also a diy
(salvaged a buncha parts I had laying around). Just tryin to find an easier
way to use phone and 5-spd at the same time without the hassle of stickin
something in my ear every time I get into the car.

I would call the manufacture service representative of the phone. The
internal lamps are run by an inverter circuit. It sounds like the
inverter may be radiating out, due to some type of internal failure.

In some models of phones, the inverter is a separate circuit module, and
in other models, it is part of one of the main boards. This is not
something you can go in and fix with a soldering iron and a meter. The
service rep would have to replace the complete board or module, and then
re-initialize the phone's programming for your provider's
specifications, and re-program the subscription data. If the phone is
out of warranty and this is the case, this may not be cost effective.

I have a V60, and the car kit installed. This phone works perfectly in
all respects. I also have a 270c, and this one had some problems. I was
able to have this one repaired by the manufacture rep while it was under
warranty.

With the sensitive issue of the very high frequencies used in these
phones, if you start soldering in the front end of sensitive areas of
the phone, it will most likely go out of alignment.

Many of the models are rigged so that when the case is opened, and or
the boards are separated, the user account is deleted. This is a
protection that they use in order to prevent piracy. The service dealer
has a jig that he can use to test the phone with his test account that
his bench instruments use. When finished, he has to put back the
customer's account information to re-activate the phone again.

You may find it cheaper to get a new phone rather than spending a lot of
time and aggravation with the one you have. This would be my approach.
