That is what is happening. It does happen when the temperature is warm.
I don't have anything extra plugged in. It seems like it happens more often now.
I have a 2008 Limited. I have a problem with the CDs automatically ejecting from the unit. Usually when this happens none of the controls on the headunit will be functional and the display will go blank. I can operate the controls on the steering wheel though. But all of the CDs will eject...
I have been lurking for a while and decided to join. I have a 2008 Limited which I love. I purchased it used in late 2009. It currently has 44K miles. I am looking forward to many years of 4Runner enjoyment.
