Bought 08 range rover sport hse 6 mnths ago with 48k on miles, love it. loaded with navi, dvd.... , last week the touch screen would not recognize being touched. common sense told me the screen would have to be replaced, however when i brought it to dealer i am told the Hard Drive is not functioning properly and they have tried re-programing it but to no avail, I was told all they could do would be to replace hard drive at a cost of $4200, thats 4thousand 2hundred american dollars... are you kidding me? It is a hard drive, can't i ship it to manufacturer to repair? does anyone have experience with this issue, i love this suv but this is a souring experience. Thanks
