Hoping someone out there has had this issue and/or can help. I am a new keeper of a Roadster. Just had her a week, and all appeared well. Driving home tonight, the touchscreen started acting oddly and froze in that I could not exit or move between screens. Thought I might recalibrate, which appears to have been a mistake. Turns out I am now stuck in calibrate mode, because having attempted 4 of the 8 steps, the screen tells me that calibration was unsuccessful and it goes back to step one. So, there I am stuck in an infinite loop of calibration failure. So, anyone "been there, done that". Or, after a week of (otherwise very happy) ownership, am I off to the service centre this weekend to sort this out? Thanks in advance. Volta.
