I realise this is an old post now, but those who have this problem manybe looking for an answer. I had the same problem, I tried a Nokia Upgrade, that didn't work. I went back to the dealer, they could make it work. My research on the net revealed that Toyota and Nokia have a slight difference of opinion about bluetooth protocols and they just won't agree. This is VERY frustrating for the customer. My solution was to buy an iphone. No problems now. BTW I have tried connecting to other phones eg HTC and Samsung with no problems at all. I am sorry to say that if you have this problem, either the Toyota or the Nokia will have to go..... or you don't get the joy of bluetooth connectivity.
