Well, that's not actually quite what you said, is it ? I really don't think
that "Sadly, parents reach a point where they need to be treated like
children" constitutes having 'robust discussions'. It actually demonstrates
an astonishingly patronising attitude to someone who has half a life more
experience than you do. But given the other content of this thread, and some
of your responses, maybe not quite so astonishing, on reflection.

**Sadly, some elderly people lose a considerable amount of their ability
to reason. This often becomes worse, as they age. I've seen this with my
mother over the last decade or so. I challenge her whenever I can, as
research suggests that challenging the elerly is the best approach to
keep their brains operating at optimum. Just recently, I purchased a new
printer for my mother. Whilst I looked on, I insisted that she should
install the printer. She did so, quite successfully. Not only do such
activities assist with her brain, but she felt a sense of
accomplishment, when she finished the job. I will always assist my
mother, when she needs help, but I will not 'molly-coddle' her.

Anyway, does anyone have a schematic for this receiver? I couldn't find
anything on the net about it except a few photos.
http://farm6.static.flickr.com/5103/5557505722_810b288c35.jpg
Got this little receiver at a flea market. It seemed mostly working, but
audio at maximum level was barely audible and heavily distorted.
Once brought home it showed traces of previous repairs (or attempts).
It turned out there was an open transistor in the audio amp stage, a
burnt resistor and two bulged capacitors. Now it works on all bands but
the VHF one, so a schematic would help to find the problem.
Thanks!

Thanks for that but it buzzes on two adapters as well as on the ac

OK: We rarely use sound on this: I suppose I can just stick a plug in
the earphone socket. Are there any more widespread consequences to
leaky caps on a unit like this please? Would they prevent the unit
charging its battery? I suspected that no one would think that a
short in the battery would be causing the buzzing!
I have done it ONCE On a Rogers Cadet 111 amplifier but I cant imagine
there can be any easy way to replace caps on a tiny circuit board like
this? (I only dared to do it on the Rogers because they were
exceptionally easy to identify, buy ones of similar values and solder
on that 1960s circuit board)

The stability of the sound circuit could depend on the battery having a low
impedance and acting like a capacitor. This would save on the need to have
extra capacitors included in the design. Then if the battery has too much
internal resistance this effect would be lost leading to parasitic
oscillations - buzz. I hope this gives you some confidence that a new
battery could cure the problem. But don't blame me if not...

It's not nice to criticize when someone asks for help -- but you should have
learned in school that a dead battery means that a device will just sort of
lie there and do nothing.
Why the unit should work properly when being powered by the 5V from the USB
cable, but otherwise produce a buzz, is not clear. How does it work when
being powered by your car's battery (that is, the plug-in cable)?
It's almost certainly not the battery. As you point out, it's difficult to
replace SMDs. I would suggest sending it back to Garmin.

No, as I said, this problem occurs when plugged into DC power,
different DC power, and AC power. Only slightly baffled why buzzing
disappears completely when side USB port is plugged into computer but
no one seems to have any ideas on this.
Really not sure what to do ACTIVELY about it as it does work fine,
with new maps so long as you don't mind no sound and having to leave
it plugged in all the time. Replacement of a numerous year old unit on
Craigslist would cost a small amount of money compared to replacement
with a refurb at Garmin AND any repair is likely to be quite
intricate. Wouldn't mind replacing the battery at about ten bucks but
am not sure that it would even WORK, not to mention get rid of sound
issue. Theoretically if this unit is over 3-4 years old, the lithium
battery may be dead AND if it hasnt been charged for some time, the
voltage would have sunk to so low a level, - for a lengthy enough
period of time that even if it weren't, it surely now is!
To recap: Leave plug in earpiece output to cut off speaker and await
whole unit failure. Take out when sound actually needed. (look for
similar unit on Craigslist for five bucks with dead battery and no
accessories and see if my battery suddenly springs it to life!)

Sorry, FWIW, for the benefit of onlookers who dont know this unit, it
has TWO usb ports: One for power in the back and a separate data-only
port to plug it into the computer at the side. It buzzes until the
side usb port is connected to a computer, - it gives a splash-screen
and then as soon as the connection is recognised, the buzzing stops.

Only caught a few of the posts in this thread, so if I'm too far off base
I apologise. Many of the cheap power supplies are half-wave (rectified
one way only instead of through a bridge. They rely on a capacitor to
modify the intermittent "DC" to a (sort of) constant voltage. It may be
that the design of the Nuvi has this capacitor within the body of the
unit, so that if this capacitor has gone down, the smoothing will be non-
existent. If the buzz is mains frequency this would support the
hypothesis. If you can find a good quality full wave power supply, and
this eliminates or markedly reduces the buzz, it would (almost) prove the
case.
