Changed to TFT DIM Retrofit speedometer on my 2013 Volvo V70 this weekend, everything on the speedometer works ok but, the radio/stereo does not work after changing to TFT DIM. The fuses are checked. The Volvo logo on the radio comes on for about 4 seconds and turns off, then turns on again, the screen here is completely black, just the Volvo logo as you see, as it turns on and off. Has anyone here have this problem? Anyone know what might have happened?
