So this is second hand info and I'm not geeky enough to know the why's but here's my take away from when I read up on the 665 before install.
The harness for the 660 which is what Victory provides looks the same as the 665 harness but is not. The result and message you are getting is consistent with results and messages others who tried that install got.
Some techies have busted open the mount and found it to be somehow different internally or at least there are those that took a soldering iron and a radio shack credit card to it, apparently without success. I don't know, maybe they did succeed. I lost interest whenever flux capacitors and solder and whatnot entered the conversation.
Maybe there is a way to make the 665 sat functions work on the handlebar if your talents lean to that kind of activity, but it's hardware, not software.
I installed the harness/ mount that came with the 665 and tied it to the Sat Nav port on the bike harness. All sources play through the bike sound system and the override functions of the GPS work but I have to control the XM and MP3 functions on the 665. Sound is fine except that when listening to MP3's I have to keep the Zumo volume at 100% or the sound cuts in and out for seconds at a time. Curious.

We can't help it
We just keep moving
It's been that way since long ago
Since the stone age chasing the great herds
We mostly go where we have to go
