Hello, I had to replace my (according to the workshop defective) HU1205, which was originally installed in the V40, because it pulled too much power in the rest state and so regularly emptied the battery. Now I bought and installed a new Kenwood KDC 455UW, whereby the SUbwoofer in the trunk no longer seems to work. Now there are four cables in the car, of which I could already identify 3 – I attach the photo times: the wide green and wide gray are clearly attached to the sockets on the radio (by ISO adapter). The right small in the picture should be the antenna (also connected by adapter). But what is the left one in the picture? That is a “subwoofernated” cable. Could it be related to the subwoofer? The radio also has 2 Cinch outputs for such purposes. Or is the fourth cable something concerning the Navi in the H1205?
