With my 300C coming closer and closer to been delivered im starting to look into mods I can do for the interior. I've been thinking about adding a in dash monitor and tv's in the headrest but im in two minds. One of the reasons is no local shop up here has worked on a 300C yet and im worried that something might go wrong just because its a newer car. I know from my past experience with my Mercedes that aftermarket systems don't really work well with newer cars with complex technology. Even though the shop I had my work done from did a good job, the system never really worked out well and I had to have removed. Im also worried if anything goes wrong with the electronics in the car that the dealer might use the aftermarket electronics as a excuse to void the warrenty. I know its a personal choice but im just wondering what you guys think about adding a aftermarket system and if you would do it or not.
