I did not have luck with this module. I connected it to a PZL radio and I had some working buttons, button it would not control both Volume and and Down (only up). It also did not allow for my phone, and other. The CAN controlled that comes by default with the Eonon is MUCH better, and it works out of the box plug and play. It also shows when my door are open and more. Skip this one unless your only option.
