Wont charge battery at all either. Battery is either completely dead
or the buzzing and the charging problem are connected somehow. *Is
there anything which can be done about this? Garmin have helpfully
offered to replace it but want something just over the used value for
the unit to do it. Not sure if it is worth spending money on it??

It works fine otherwise and has updated maps. Don't know what features
newer units have which I might need.

Could buzzing be a short in the battery which could be fixed simply by
replacing the battery? Or should i just disconnect the speaker somehow
pending someone figuring out what is wrong with it?

if the battery charger is defective, it would / could cause buzzing.
Technically, the charger might be putting out AC instead of DC.

Thanks for that but it buzzes on two adapters as well as on the ac
adapter which I have to use in home while trying to figure out what is
going on with this unit:

If the buzzing is caused by something in the device itself, I would
check for faulty capacitors.

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...
