Source note on shared footage
We have a massive and growing video library, but we don't have everything...yet.
Car companies often use the same engines in different cars. They also slightly alter the styling and sell the same car by two different names (amongst other tricks to help offset development costs).
Our system selects the most applicable video for your car based, in part, on these characteristics. The video displayed may not look exactly like your car, but may be relevant enough for you to get a good idea how to do it.

我们有一个庞大且不断增长的视频资料库，但还没有全部内容……
汽车制造商经常在不同车型中使用相同的发动机。 它们还略微调整了外观设计，并以两个不同的名称销售同一款车（以及其他一些技巧，以帮助抵消开发成本）。
我们的系统会根据这些特性，部分地选择最适合您车辆的视频。 视频中显示的内容可能与您的车辆外观不完全相同，但可能足够相关，让您了解如何操作。
Procedure notes
This is how to pair your iPhone or Android phone to a 1991 GMC C2500. 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 1991 C2500. 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 C2500? 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 1991 C2500 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 C2500 will not allow additional devices to be paired without deleting some first. If your 1991 GMC C2500 requires a password, try 1234, 0000 or ABCD.
