Hi, I'm a newbie to this forum but was wondering if anybody had any advice regarding the below issue. I have recently purchased a 2006 (56) W209 CLK 320. The car comes with COMAND sat nav etc. However, it appears that when using the sat-nav, you have to know the postcode and street name. You do not seem able to be able to simply input the full postcode as a destination. Is this correct, or am I missing something? Also, the system does not seem to be able to pair with my iphone 5. Infact, I don't think my phone even sees the system. Would there be an update disk that may solve the above problems? Also, there doesn't appear to be a manual for the system. A manual could well shed some light on the above issues as well. I have looked around and don't think there are any downloadable PDF versions. Does anybody know how I would go about getting one? Thanks in advance for any help anybody can offer!
