Hi, This might be a discussed topic but I did not found details i can use. So, I have this F900BT installed on a Toyota Hilux 2010 and I would like to connect the unit to the car steering whell controls. For this I understood that I need an adaptor/inteface. Can someone direct me please to few producers selling this type of connectors as after hours of googling still cant find anything certain. Thanks, Paul.
