Magellan GPS 315

My GPS is getting on in age and I think it would be time for a Lithium
Battery change.
Anyone know of any repair shops, or a manual on how to go about this.
Magellan will only sell me another GPS on it's Trade in Policy.
Thanks

Do you mean the lithium backup battery?

They're supposed to last at least 10 years. I have a couple of
pieces of equipment that are older than 10 years and the lithium
backup batteries are still holding up great.

Unless you're losing your locations and waypoints etc when you
remove the AA cells, there's no need to replace the lithium battery.

Don't worry about it until at least 2010 :)

The GPS 315 doesn't have a lithium battery, but should work well with
two of the disposable AA lithium batteries, at least mine does.

It's got one of those tiny 'button' type lithium cells tucked out of
sight hidden the circuitry. It holds the waypoints etc when the AA batteries
are removed. It's not user accessible, but the average life is 10+ yrs.

Thanks for the info guys.
What I want to do is change the Backup Battery in the 315. At its age it may
need it soon and I don't want to find out while I'm in the bush:-(( If
they used to be repairable there has to be an instruction manual somewhere
on how to break the case open.
