Sorry, taken with my phone, but this is what the OEM (?) adaoter looks like
that was in my van and I bought a Volvo adapter that works with the last two
stereos.  This one is from by Bluetooth headset, but looks the same only a
little smaller. I have not noticed a marked difference if I use the local
option on receiver, but again, it only happens once in awhile.
