Replacing stock radio for something with SAT NAV (RCD 330+ maybe)??

[kev__]

Hey guys,

I just purchased a 2013 Polo GTI, the stock radio works but it lacks sat nav and car play.

from the bit of reading i've done i think i need to get the RCD330+? or am i wrong?

if this is the correct unit, is it compatible with the polo and can i retain my steering wheel functions ?

any help is greatly appreciated

thanks in advance guys
