Bought a 2011 key/dvd update for my 2006.5. 2011 Installed fine, rebooted all the way to megatouch force splash screen then KEY RANGE MISMATCH. Searching I see there was a patch for this or is there another way around it. I reinstalled software no go, cleaned key holder bent pin slightly. I put 2006.5 back in and it booted fine.
