Bought a RR vogue 2004- was told by garage sat nav cd would follow. Fast forward 5 months and they have sent me a DVD mine is a CD system. Been to LR garage who were as helpful as usual- asked if I could try part no YIW500050 in my unit to see whether unit works- they had one there- but no I had to buy it at £160. Asked if they could check unit- another £150- just to test let alone fix if broken! Found a co who will repair unit if faulty but I need to send the correct CD with the unit. Anyone got one I could try- I would return by special delivery- or any idea where I can get the correct one for a siemens unit YIB500040 to enable me to get it sorted? Cheers
