Navigon 2100 down... Need assistance please!
Have a Navigon 2100 I bought used a few years back and have proudly relied on for quite a while. Battery finally stopped holding a charge, so following a YouTube video, carefully opened unit & removed battery, matched part # & specs on eBay, ordered, & carefully installed a new battery, making sure the ribbon cable slid into position and was locked properly, and reassembled with great care. Recharged overnight, but upon powering up, I hear a few musical notes, then the screen slowly changes from one solid primary color to another. Activating the "reset" button has no effect, either as powering up or during operation. Will turn on & off fine, but no other functions except mentioned above. Any suggestions how to return my 2100 to service? Much rather repair than replace, since Santa got all my funds recently. What do you think???
