Just because you realize you're paranoid - doesn't mean that they're NOT out to get you!
Say... Where did that black helicopter go????
Frankly - I'm a NAV 6.1 owner that would like to downgrade... As I was driving yesterday and needed to make a call, I tried in vain to make the phone's number buttons on the NAV screen register that I was pushing them and got not a beep or whistle that they were disabled. They were even fully lit-up!.
So - what did I do? I pulled my Treo 700P cell phone out of my pocket and pulled up the dial screen and dialed the number and completed the call via Bluetooth..
Now - all that fumbling around for the phone - think about it - it would have been FAR safer for me to just have access to the bloody buttons on the NAV screen wouldn't it?
Toyota - are you listening???
