I'm already annoyed by a non-funtioning infrared remote control for the first time.
I've already bent contacts, soldered bridges and tried other things. I thought of my old sparkle! 
(I ordered this for my 100' Audi at Conrad) Now my question, Can I just disconnect the infrared receiver and connect my radio unit?? Because of alarm and compensating (which is supported by the radio unit) Does anyone have any idea or this already??Thank you in advance! Greetings René
