Wow you have documented your problem well. My 96 Audi has similar
except is hash sound. Most noticable
arriving home listening to 1080, audio is half buried in noise till I
kill the engine, then audio is clear.
Everywhere one looks, the AM band just gets dumped on. As compensation
you would at least think,
they would put in HD radios so one could get the sister FM station relay
of the AM side. Wouldn't
generally help in the country of course... You could try a super duper
(ugly) AM antenna with coil, etc and
maybe a separate radio that's not hooked up to every modern doodad in
the car (ugly). Or... stream
internet (ugly sound and ugly just thinking about it.) How about,
record what you like from home and
listen on a day delay basis... or just listen to the podcast of:
