Re: Furuno GPS Navigator GP-90

On page 9-2 it has this about the battery:


It looks like it is not meant to be user replaceable however it may be possible.

CR2450-F2ST2L is a CR2450 button cell battery, 3v Lithium.  It will be easy to get the battery but replacement could be a pain if it was soldiered in.

I hope this helps!
