 * This is an implementation for remote controlling 8227L based Chinese Android players. These are called Junsun, Mekede, etc.
 * In order to make it work, you need to select 108. Peugeot206/207/307 from the CAN Type settings.
 * This library is tied to the Android unit and not to the car's model. So you don't have to have a Peugeot car to make this library work.
 * You can interface any car as long as you implement whatever protocol it uses.
