First test the radio successes without installation, simply plug and tasted cable, screwed additionally stops the frame. So far everything has worked wonderfully.
But! the frame is too large, so that one no longer gets over the appliqué. The frame is compressed above. Had then a piece of the upper web ca 1mm cut off, but fits better trim still does not fit. To top it all hassles of wiring harness is disposable. Since I have a Kenwood radio, I have 2 adapters. BMW to ISO on Kennwood. Looking for space for the cables, I have staked the tree a few times and. Out to contacts have solved. Did it put in order but somewhere current no longer flows.
Can only advise on the product.
