This item is the dealer version and comes in no retail packaging. Only suitable for a Fully working system.If you don’t have a functioning original disc or your Satellite Navigation System Screen display “Check Disc” error message then please don’t purchase. Unfortunately some sellers when selling their car remove the disc when the Sat Nav unit has a fault, to disguise this they remove the dvd from the unit, generally telling unsuspecting buyers that the disc has been lost but in reality the Sat Nav unit is faulty. If your satellite Navigation works without a disc then you have the HDD or SSD version and this disc will not help. You will receive a professionally authored and electronically verified backup disc.
