Per your questions based on what I and others have experienced. It doesn't seem to happen to every Roadster, but seems to be happening to a significant amount of them. To be clear the VMS is the computer under the passenger seat with 2 connectors, The VDS is the display on the center or left side ( 1.5's). Resetting the VDS does not pull the power from the OEM GPS unit, only pulling power from the VMS will do that! 1. If your VDS has not been powered off since the week rollover issue started, you won't see the symptoms. Its not the VDS but the VMS computer, but normally yes, it only seems to occur when the OEM onboard GPS connected to the VMS is powered down or the whole car is shut down for PEM cleaning. 2. You need to pull the power on your VDS and plug it back in to test if you have this issue. As stated above its the VMS computer NOT the VDS display that needs to be reset. But in reference to your questions, Yes, that should power down the GPS and reset it. Once its reset or the VMS is reset, you should see the "weird" date issue. 3. If the date/time is wrong on your VDS after power cycle, then you have this issue Seems some of the cars show the right time, just the date is off. Altitude and direction show correctly in the VDS, just the time is wrong. It will also show up in your car logs when you extract themas well. All the dates of each LOG entry will be based on the erroneous date/time stamp used by the VMS computer Hope this helps!
