Would a new HU be useful: – mp3 capable – very good radio reception – good sound – high pass filter (every other thing I don’t care, except possibly still half good design, so please no blinky-blinky pinball optics ) Price as cheap as possible up to 500 EUR!! The entry model of Alpine (200 EUR) even has an HPF, but the Alpines should only be on average in the reception, right?
