will the rcd330+ replace the rcd500, do I need additional equipment or does it just plug and play? I have sterring hweel controls but they dont work with rcd500 unit, no bluetooth.
If your car was produced before 2009, it will have battery drainage problems. If you have an 8-button multi-function steering wheel, it cannot directly control RCD330 plus. CANBUS simulator can solve the battery drainage problem as well as the 8-button The multi-function steering wheel control problem.
If your car has a 12-button multifunction steering wheel (or a 6-button multifunction steering wheel with only the right button), you can directly replace the old unit with RCD330 plus without any simulator and adapter.
