I have a navman S50 3D a couple of years old, updated maps all fine.
It sat in the draw for a couple months then would not load maps etc. reloaded from laptop all ok, now if it is not in use drops all data.
I have just removed all screws ready to look for an internal battery,before l destroy it can anyone tell me Will i find a battery.
Even with the screws out it do'es not want to come apart
Thanks for any help
