I can't speak for how BMW handles things in Belgium (where the OP is) but I can say that years of experience with BMW service in the US has proven that warranty coverage hassles resulting from non factory installs and/or aftermarket items are a real headache. If a dealer can do the install it helps but then again the cost of that likely nullifies any benefit to not ordering it with whatever option. Also the value of the car can take a hit as a result of mods too. Changing the headliner to black would be safe though assuming it doesnt impact any airbags, no idea what that would cost
