Duh- I found it, misplaced fuse under hood! Blaring and obvious with a clear head and advice to triple check. Thanks for your support!

I appreciate the responses- I have checked all the fuses both under hood and under dash, it seems wrong though that there is no power to any of the radio related fuses with the key on (64,65,66,43).
Power feed fuses and connections from under hood are all ok.
All the unused fuse slots under dash have no opening to put a fuse into.

64. Audio system, Volvo Navigation system (option), 5A
65. Audio system, 5A
66. Audio system control module (ICM), climate system, 10A
67. Not in use

Fuses under the dash.

Did you also pull the relays (1-18) in the engine compartment?

Keeping it running is better than buying new

I would disconnect the battery (do you have the radio code?), then I would look at all the fuses and the female sockets in all the fuse blocks in the car. Check your owner's manual for their locations.

You may have touched something wrong and blew a fuse further up the line.

This may seem like a silly idea, but it costs you little and you may find a bad fuse, a corroded socket, of fix a bad connection in the process.

You should also check the location of each fuse in the process - you may have put one of the fuses back in the wrong location as some sockets are usually left empty.
