Yesterday I downloaded a map update and a software update. After disconnecting from the computer I turned the unit on but after about a minute or two the unit turned itself off. After turning it for a second time I noticed that the battery indicator was only showing one green bar, so I connected the unit to a battery charger. After the battery indicator showed all green bars I disconnected the charger and switched off the unit. I then turned the unit back on, all power bars were green, but again after about two minutes the unit turned it self off, so I turned it on again the battery indicator was showing only one green bar and after two minutes the unit turned it self off.
Any idea what the problem could be?
Could it be that the battery needs replacing?
