hi all im looking at upgrading my cd player in my 2005 gti, i assume i have the rcd300
is it a simple un plug on old unit and plug the new one in?
i assume as it is a sat nav unit i will need to mount a gps antenna somewhere?
am i right in thinking that this unit hasnt got the dreaded battery drain issue?
and lastly will my cd changer plug straight in? (as this ss the main reason i want to upgrade as my unit has some very UN-sophisticated after market ipod connector which has disabled the cd changer, the main thing that draws me to the 310 is that it has a aux input on the unit it self as this is what ill be using as my main source of music
oh and where are the maps stored? on a cd or sd card?
