Hi Guys. As much as I'm enjoying my car (CLS 55) I do feel the nav and command unit feels a little dated compared to some of the current units on the market. I came across a Dynavin D99 headunit which looks very much like the OEM unit but has a host of nicities such as touch screen, updated nav, Bluetooth, iPod connection etc. It just seems like an all round good system that does everything you want it to which unfortunately my current unit does not. I just wanted to know if any of you have had any experience with the unit? Would it be worth making the change for the £600-700 odd quid it is plus the installation and would it totally intergrate with the Logic 7 system in the car? Your thoughts and opinions would be welcome. Foz.
