Hi, first time i am looking for a GPS for cars, this time is for C220 2011/11 Break... It has the original GPS and have 1 card reader slot empty, i think i have to insert a card reader with the new maps update? Thanks
then, you have an APS COMAND NTG4 W204 with an internal 40go hard disk and 2 slots : 1 for DVD and a second one for PCMCIA Multi Card Reader (same as mine)
But ... you'll need an activation code for the map (obtained with the VIN number of your car) Even if you can get map for free with the link above, it should be safer asking price of map + activation code at your dealer than to ask and pay for a code on other forums.
