Had an interesting issue this weekend where my VISION Display froze on my 2011 22v. I would turn the key and the system will load and go to the main screen but there all the numbers and gauges are greyed out. No fuel gauge, no tachometer, no speedometer, no oil pressure, no ballast control, etc. This also includes the psuedo analog gauges in the cluster. Everything is controlled by that computer. The only things I can do is turn the engine over and adjust the stereo.
I have tried reseating the fuses under the dash, and on the engine itself. I also tried reseating the connectors on the foreward side of the engine as well as under the dash. Both batteries have good voltage. I do believe there is a new firmware version for this but whatever it is just a simple reboot isn't fixing it.
I have a call into my dealer and he's researching the problem for me but I'm looking for some other recommendations from owners.
Thanks
Dave.
