Ok, so this is exactly what I've done;
Take out MY07 86201AG281 PF-2824I McIntosh leaving existing wiring in place.
Connect squarish plug from Anycar 1080C into back of HU. Connect AUX from back of Anycar (not the MIC) to iPhone. Connect charging port from Anycar to bottom of iPhone. iPhone is an iPhone 4.
___________
This is the original setting for the Clarion:
2 switches pointing to OFF
2 switches point to ON
NO HU response
Repeat 2x = NO
Scan 2x = NO
CD 2x = NO
Power Light = NO
Reset button on Anycar = Doesn't appear to do anything.
Power to device = YES
___________
Opposite setting:
2 switches pointing to ON
2 switches point to OFF
YES HU response
Repeat 2x = NO
Scan 2x = NO
CD 2x = NO
Power Light = YES
Reset button on Anycar = Doesn't appear to do anything.
Power to device = YES

This is the setting for Subaru:

So yeah, not sure what I'm doing wrong.
