Matt100 1 Report post Posted May 17, 2019 Hey, Hope you can help. I randomly, lost all FM and AM signal on the BRZ. - CDs, USB work fine. It's still got the standard crappy green head unit fitted, and I realise after doing some reading / what research I could that the aerial is actually amiplified from a 12V pinout on the head unit itself. So, before I go throwing money at head units, is there anything I should be checking which is a "usual" culript for loosing FM and AM signal? I've checked the antenna is still plugged in to the back of the head unit which it is Cheers! Share this post Link to post Share on other sites
