My Navigon 8110 navigation system is now 6 years old. The battery holds engergy only for a few minutes. Software and functionality of the Navigon 8110 is still nice, therefore I would like to replace the battery instead of buying a new navigation system. 2 questions: Where to get a replacement battery? How to open the device and replace the battery? Many thanks for your help
Reinhard Schramm, here is a good video that shows you the how to. As for where to buy a battery, that will depend on your geographic location. It is available at places like this. Hope this helps, good luck.
