I don't mind the ambient lightings, some of the colors I am not hip on but they can be left off if you wish. DRL, I wish they had them here in US. I run with mine 24/7 for safety. It really does increase the chance of others seeing you on the road.
I personally plugged into the "spare" (19 I think) fuse slot for my trailer wiring. You have to leave the cover off (put it in the glove box) and took a 3/8" eyelet and cut 2/3 of th loop off so that all that was left was a "flat blade" on one side that is th size of a fuse blade and pushed that into the "power" side. I then atatched an inline fuse then crimped it to my 14g wire to the trunk. It was easy to do and didn't involve any drilling or digging to fish out a wire in the engine compartment. I had tried that first and got "frustrated" and went this route. Pretty happy with how it worked out.
Sat radio never sounds as good as a regular FM or especially a CD. I will say that it sounds a lot better in my Fusion than my wife's 300 Touring. I am thinking the newer satelite radios do better. Both cars have best sound option from the factory.
