There was some discussion of this here: http://www.teslamotors.com/forum/forums/air-conditioner-issues?page=1
but that thread was mostly about A/C compressor noise, so I wanted to start a new one.
I have experienced several times now where various electronics hang up and cycle on and off - it seems to be related to CPU capacity. I am pretty sure each time it happened I was doing a big zoom-in or zoom-out on the map, and that caused the A/C to shut off for several seconds at a time, radio volume controls did not work, and some other commands did not respond. After a delay, those commands kicked in (e.g., the radio volume suddenly shot way up or down, depending on which way I had been pushing the button with no apparent response).
Not sure if this is an inherent limit (e.g., based on processor size/speed, amount of RAM) or if it can be corrected with some software download (maybe reprioritize processor usage?). The map - sadly - is already not too fast, and that's one of my minor complaints about the car. But I don't think it makes to try to speed the map up by shutting down (even temporarily) other systems!
Any experience with or thoughts on this issue? Any known fixes?
