Pair a Bluetooth Phone to a 1990 Mercedes-Benz 300D 2.5 2.5L 5 Cyl. Turbo Diesel

This is how to pair your iPhone or Android phone to a 1990 Mercedes-Benz 300D. Generally, pairing a Bluetooth compatible phone to your car will allow you to make handsfree calls. In many models, you can also play music through a paired device over the Bluetooth connection too. Check your owners manual to see if this is possible in your 1990 300D. Some models only allow Bluetooth devices to take calls wirelessly and do not support Bluetooth music. Typically, these cars will require an input jack to play music from your phone.

Do you have Bluetooth problems? Is Sync not working in your 300D? Or are you having Bluetooth issues? The steps needed to sync your phone to your car tend to vary substantially from one vehicle to the next. If you followed the steps in the video above and your a 1990 300D will not connect to your phone, then you may need to delete some saved phones. Used cars will often have several saved phones in them. Once a maximum number has been reached, the 300D will not allow additional devices to be paired without deleting some first. If your 1990 Mercedes-Benz 300D requires a password, try 1234, 0000 or ABCD.
