Is this a known problem please? Buzzes continuously except when

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.
