[QUOTE="Creedence85, post: 168122, member: 4346"] The problem is caused by the GPS clock roll over bug which is kind of like the Y2K of early GPS systems. More info on the GPS roll over: [URL="https://techcrunch.com/2019/04/06/gps-rollover-is-today-heres-why-devices-might-get-wacky/"]GPS Rollover is today. Here’s why devices might get wacky – TechCrunch[/URL] The Denso nav units in the 2005-2010 Corvettes and some other GM vehicles used a 10 bit clock signal which only goes up to 1024 weeks (18.3 years), starts at Jan. 1, 2000, hit the roll over earlier this year, and then goes blank after that. Denso would need to release a firmware upgrade which could update the 10 bit clock signal to the new 13 bit (presuming it's all software and not hardware), or allow for the clock to be set manually. 2011-2013 nav units aren't affected because Denso updated them to use the 13 bit clock signal. There is a sticky in the C6 section of corvetteforum.com with no solution yet. I haven't disconnected my battery since before the new year, so am now concerned about how to work on the car, and appreciating that I may end up losing the clock when I do if I don't reliably retain power with another source. There are also reports of some nav units losing the clock after the roll over without battery disconnect. [/QUOTE]
