hi i have audi a4 b8 with a Concert lll radio. I am having issues with conecting my phone. the phone conects fine but will not download or show phonebook. i have tried all web ideas but no sucsess. Now i have found out that the software version is sw0210 and aparently in order for it to work with phone it needs to be sw0310 It also aparently alows the use of larger sd card. Has anyone else had this problem? Is there a way of updating it youself of is it a audi job? cheers dave
