I have 2012 model. Pair it with phone/audio should work. Make sure your phone bluetooth is on BEFORE you turn on ignition. I dunno why. It is fiddly but mine works well as per above.
Can you put up pics of your spray on, what brand, what did you pay, how even did they do the edges around the lip, did they score the tray first or did they use an adhesive etc
I am happy with mine. I agree with some members that the build quality is good but not great and there are more powerful trucks out there but for the price you really can't complain.
I am happy to recommend the D22. I have not had it off road yet and using it mainly driving to work, family outings and the like but they look great and its nice to know the 4x4 is available if needed.
