Could the Steering Wheel Control work after DVD GPS Unit installation?
Many cars have steering wheel control in the original CD radio player. when you want to replace the car radio
replacement with DVD player, you need to figure out the steering wheel control could be used or not. Will the
owners lose the steering wheel control? The answer is no.
First you need to check out your original CD player has the can bus or not. If it has, you need to clear this. it is
sure that the procedure will be easier if your car doesn’t have can bus. You just need to connect the steering
wheel control wire with the car DVD player. Then set up the steering wheel control to make it work. There are
some cars which do not have the can bus, such as Hyundai, Kia, Nissan and Toyota, and some cars of VW,
Honda, and some others. These kinds of cars are easy to install a 2 din universal car DVD gps player for most of
these cars. They are easy to make the steering wheel control to work.
For the cars with can bus, you need to be careful about it, such as VW cars, BMW cars, AUDI cars and so on…all
of these need the can bus to make the steering wheel control work. For these cars, you need to install the car
DVD player with can bus, if you need to use the steering wheel control. There are many special designed car
DVD gps for the car, especially for the car with can bus. You do not need to set up the steering wheel control for
these cars, since the can bus is specialized for the car.
For the cars with the can bus, it’s possible that some of the steering wheel control function can not cooperate
with the can bus 100%. That’s because the can bus is a little different from the different countries. For instance,
the opel cars are different in China, in outlook and inside, and the original electronics system. According to the
feedback, some of the ope car DVD players can not work very well with the steering wheel control and
computer. For the other models, such as car DVD gps player for mazda 3, audi a4, they are working well.
