Car: Audi 80 B4 (8C) 2.0 E Radio: Pioneer MVH-X350BT Dearest technical talent, I recently expanded the original “Audi Beta” radio in my Audi and replaced it with the above-mentioned radio. As the old radio ran over timeplus, an ignition plus was not installed. For the new radio I needed beside antenna adapter and ISO adapter also an ignition plus. I got this from the ignition lock, so that the radio as soon as the key plugs ect.. Now there is a problem with the radio reception, which was not available before:Who What How? – Engine off: radio reception super – Ignition on: radio reception super – Engine on: radio reception super – Give gas (without gear): radio becomes quiet + bad empfag – Decoupling or gas off at 30km/h: radio reception suddenly better – Decoupling or gas off at 140km/h: radio reception remains badMy idea: – Ignition plus from the ignition lock not disturbed (buy capacitor?) – Mass cable not connected properly?
