Yes, because I like tech and eye candy.
Retrofitted an OEM navi in my old A4 (got to love eBay sellers from Eastern Europe).
Ordered it for my old C300 - despite the sales person saying, "Why don't you use those suction cup ones and save a few grand?" My answer, "Don't like things cluttering my windshield and I like all the extra features that come with the navi option".
Ordered it with my current E90. Funny thing though, the head unit had to be replaced because I got the red startup screen and the DVD drive not reading my DVDs. Not sure how common this is, but mind you my E90 was in an accident.
