Radio switching to IPOD when car put in reverse

[misst23]

I bought my G37 when they first came out - and I have about 9000 miles on it. The only issue that I have had is when I switch my car into reverse - my radio is automatically switching to my IPOD. My radio could be on XM, an FM station or even not on at all. My car is currently in the shop for the second time in a month. The first time, they kept it a week and the only solution was to swap out the entire audio system. This did not work - which is why my car is back at the dealer. Has anyone seen or heard anything like this??

Update - I just found another thread where they are talking about this. Sorry!!
