Bluetooth connection problems
A. Search for the unit on your phone and select the device named CAR KIT ( may also be named by brand&model ). Enter the default password for your unit (0000/8888/1234).
You can now place and receive calls through the unit.
B. If you had another unit previously, go to your phones bluetooth settings and "forget" the old device to make sure there is no conflicting names etc.
C. Try a different phone to make sure the problem is within the unit.
