I just bought new tires and the guy at the tire store told me that the reason my old tires wore out so quickly was because I never rotated them. I had no idea. They said I should have my tires rotated every 5000 miles but I'm never going to remember that, and I don't drive a consistent number of miles each week to figure out when in the future that'd occur. Can my Toyota Camry remind me when it's time to rotate the tires?

I have and really like the GPS navigational system on my Toyota Highlander but am a bit baffled about something: it seems that my cellphone can't auto-pair with the bluetooth system in the car because it's no longer the #1 phone on the list, my wife's phone is in that slot somehow. Not good. How can I delete her cellphone so mine is #1 and the bluetooth system pairs automatically?

Just picked up a used Toyota Sienna van and I'm pretty psyched about it - lots of room and it's really comfortable to drive - but I'm not sure how to pair my Apple iPhone 4 with the navigational system from Toyota. Any help or tips? Before you ask, yes, the car does have Bluetooth as far as I can tell.
