By chance I heard about the possibility of my Tom Tom to spendieren a new battery, .eigentlich I wanted to dispose of the Navi, it had only played crazy, The delivery took place after 40 hours and the Warensendung. Thanks to the guidance in Youtube changing the battery was not a problem. Just be aware and the small end side pull-delicate woman hands helped me ....................... I have connected the navigation equal to the onboard system and it works so far. For me, a very good buy.
Only after charging at the power of the battery has been fully charged. I suspect that one achieves a 100% charge on the 12-volt cigarette lighter charger cable only without a home if you drive a long distance.
