I hate to say it, but older electronics are not worth repairing. They are
the disposable lighters of our time. Your are correct about compromising
the water seal with any attempt to repair. Look in any catalog and you will
be shocked at how inexpensive a new (and better) GPS is. A repairman could
not charge little enough to make a repair competitive.

I have a Lowrance Globalnav310 in for repair.
The fault doesnt seem to be much of a problem but it defies me to even
open
up the case. The only way in that i can figure is almost certainly going
to
seiously compomise its water resistance. therefore making it virtualy
useless for the job its designed to do.
The manual downloadable from the Lowrance site was as expected an "how to
plug it in and what buttons to press thing", hence useless!
It is of course way out of guarantee and marine electronics companies are
notorious for the line "we dont support our old product lines. would you
like to buy a new one?"
has anyone any suggestions?
thanks in advance
