My wife hated the back pad on the Givi I had on my ST1300, so I replaced it with a Mustang back pad (used a cruiser model) and she was much happier. I used a hinge to mount the mustang back pad so the Givi box could still be opened.
I have a V46 on my DL650 now, and knowing she wouldn't like the back pad, I didn't get one and figured I'd put another back rest on it like before. But she has been okay without a pad so far (her jacket does have padding).
I've also talked to others who've had issues with the Givi pad (and I use that term loosely), so you are not alone.
