The A3 8P and the A4 8E B6/B7 units are virtually the same, at least in regards to the RNS-E. So your apdater should be fine if you have a an A3 8P and got an A4 8E adapter.
Problem 1: Did you confirm that the unit is coded for an A3? If yes, did you do a reset (saving 1 in adaptaton 111 or pressing RADIO and SETUP until unit reboots)? If both didn't help, does the unit illuminate if you turn on the lights?
Problem 2: Do you have the standard sound system and not Bose because the adapter looks like it's for a non-Bose system. And is the unit coded for non-Bose?
Problem 3: If you are in NAVI mode and go to SETUP, is Show Compass checked? If it is checked it will show NE in the middle part of the DIS even if you are not navigating. Turn Compass off and you will see the temp moving to the middle section of the DIS.
