I installed a Idatalink maestro with a pioneer nex8000 and have installed the updates and have a ford sync system. but the maestro is unable to get VIN onfo when i set it up. i made sure the wire is connected to the white and white/blue of OBDII port. also i had a frd-11 by pac audio and all feature worked except steering controld with boss steering wheel. but now i cannot get the dimmer to work and neither will the radio stay on when i turn the key to off position. it used to stay on untill i opened the door but now it will not do it. i have replaced the maestro unit under warranty thinking it would be bad and reprogrammed it but still wont work.
