I have a March 2014 DAB Columbus for sale (3T0035686H) coming out of my car Octavia prior to me moving on to a younger model.    It has the SSD 30gb hard drive, firmware version 6270 and map version 8536, which is the latest v16 at time of posting.  This unit is in good condition and has worked perfectly in my Octavia for four years.  Before I removed my MDI unit it also worked well with that, and it currently works with any of a CD changer, aux in, phone media player via bluetooth or
