My C320 won't connect to my phone via blue tooth

yes, this is a new to me car. i followed the manual but nothing no connection

Assuming your phone and car are both Bluetooth capable - you need to activate the search function on the car and the discover function on the phone. There is usually a timeout function (maybe a minute or two) that you have to turn both of them on together.

i have a 2002 c320 with no instruction how to paip my phone to the car
