USB port help
 

I just added nav extension module to my FRS 10 series. After Adding the module and reconnecting everything, my USB no longer works! I've taken headunit back out, and unplugged and reconnected everything again to no avail. I believe I saw that the small grey connector is the USB one (wire seems to lead to USB port) Has anyone else had this issue, and does anyone have any suggestions? Nav extension shouldn't disable USB port, right?

I tried search, no luck. No one in the DIY nav install thread seemed to have this issue.

Figured out. Must make sure USB plugs into extension module, not into head unit (old spot)
