I have a volvo V70R 2005. The radio HU850 will not work. If the car is running for a long time (45min) It will sometimes work but only on channel 3 and only through the front speaker. The channel display is always working but no sound (no output) The dealer told me it needed a new amplifier booster which is located under the passenger seat. I replaced this with a used booster but it did not fix the problem. Do I need a new radio itself or is it more likely the amplifier booster I put in was also bad?
have the same problem?
