I have a 2001VW Passat. Last year I changed the original head unit and replaced with a Sony head unit.
On the original head unit I got good reception on both FM and AM frequencies.
When I changed the head unit I noticed on AM the reception was almost non existent. I don’t listen to AM very much so I had no issue with it. Recently two FM radio stations (triple m and gold 104) have started to get poor reception while all other stations are fine.
I have checked connection at the back of head unit and replaced the plug that connects the antenna cable into the head unit as it was a little loose. No help.
I bought a $25 screw in antenna from supercheap to see if that made a difference thinking maybe faulty antenna. It was actually much much worse with the new screw in antenna and pretty much lost all reception.
Has anyone else had this issue? Could it be faulty head unit? Any advice would be appreciated.
