I just picked up my new 2010 Prius with nav unit. I have a sony ericsson z520a phone. I was able to connect the phone to the nav and send/receive calls. But I cannot transfer my contacts to the car. It seems like this service depends on the Bluetooth OPP profile which I'm told the z520a does not support. Have anyone else been tripped up over this and have a solution short of buying a new phone?
