I have a 05 C-230 without the factory navigation. I'm wanting navigation, but haven't heard the best things about the factory nav units. BUT, if I go with an aftermarket navigation unit, I want it to look as factory as possible. I've seen only one picture of one installed and it didn't look very good in my opinion. I'd like a really good looking dash kit to make it look close to factory. Any one have any input or pics? Thanks in advance!
