installed the multimedia interface on my BMW X5 2013 i already have a nag and a rear camera,I have 3 issues with he installation i bought this from you guys http://www.ebay.com/itm/251442160772?ss ... 1497.l2649
I installed it and i have image but no sound. i installed a civic one but no sound is pushed.
here are my 3 problems
1- no sound , i have dip switch 1 and 2 pushed on. i am connected on av 1
2- i cannot control anything from the drive how do i change aux from the idirve?
3- The installation instructions are very unclear i have some extra parts i am guessing those are for people who don't have a rear camera or a nag?
