Looking at trading in my 04 C230k on a 07 C230. How can I tell if it has nav.? when I push the nav or map button it says to insert the nav cd. Does this mean it has the nav installed? Another I looked at said nav not available when I pushed the nav button, but it was an 06 model

 

The navigation unit for the 2005+ 203s comes with a wide screen (no display). US specs have a screen that folds away to show two different slots: one for music CDs, one for the nav.DVD.

The Euro unit only has one slot.

Then there is the possibility to check the car's VIN in your dealer's EPC.They should be able to tell you exactly what head unit the car came with from factory (assuming the original unit is still in the dash).
