Rnse a4 b7 garage ripping me off
Bought my a4 sline b7 7 weeks ago with no stereo and they told me that the stereo was on order. I called them every other day for 3 weeks until they told me they have one that will play music but no sat nav doesn't work. So I took they temporary one ( which I assume was the one originally in the car ) just to have some music over Christmas but I am left waiting again calling them and they are coming up with different stories on how hard they are to come across. Now I've found loads some even on eBay that look exactly the same as the one I have that works so I told them trying to speed them up and save them some money. Now they are telling me that the one I told them about wouldn't work although it is exactly the same I have phoned trading standards but they just said send a letter of complaint.
Are there different codes on the rnse specific to models or are they having me on ?
