I've added the North American market OEM trailer hitch to my V60 Cross Country. There's not a lot of detailed information out there on this hitch; in the interest of helping the next guy, here's everything I know.
Installed price: $1807: parts $1311, labor $348, shop fee $25; sales tax $123 (dealership installation, April 2020)
Receiver size: 1 1/4"
Receiver height (top inside edge to ground): 14 1/4"
Ball height with factory tow bar (top of ball to ground): 17 3/4"
Electrical connector: 7 pin round (fixed to receiver ... no additional cable)
The hitch is completely invisible when stowed ... no trace of it shows. I'll add pictures to this thread from a few different angles.
The OEM hitch kit includes software to map the hitch to the V60's stability control and dash warning lights. A new hitch release switch is mounted just inside the cargo area on the right rear side panel. Pressing the switch releases the hitch and it swings down from the vehicle. Pull the hitch up by hand into the towing position and it locks firmly/positively in place. Stowing the hitch is the reverse of this process; press the release switch, and swing the hitch into stowed position. The tow bar is a one-piece bar/ball combo with a 2" ball and 1/2" diameter hitch pin connection. It must be removed from the receiver before moving the hitch to the stowed position. It comes with a storage bag to keep it rattle-free and wedges into the wheel well that holds the spare tire.
For my application (Yakima Rack and Roll trailer), I need a 22" ball height. Replacing the tow bar with a 5" riser and 2" ball (about $35 total) will get me to a 21 1/4" ball height. That's as close as I can come to 22" ... I can't find a riser greater than 5" for a 1 1/4" receiver. I also need a 7 pin to 4 pin adapter which can handle LED lights (about $25) to connect my trailer's lighting. The Yakima trailer has LED lights and uses a flat 4 connector.
Although the hitch is expensive, it was only $100 more than a local custom shop quoted for an installed Stealth rack/tow combo with active software, and Stealth doesn't seem to offer a hitch riser greater than 2 1/2". The Stealth comes with a 2" receiver, but the unbraked towing capacity of the V60 CC is only 1650 lbs. 1 1/4" hitches like the OEM hitch can handle that load easily. My Yakima trailer loaded with two fishing kayaks weighs 350 lbs, including the trailer. Bottom line: I felt the benefits of Volvo's own software and a factory/dealer warranty on the install was easily worth the $100 difference in price.
I'll add to this post after I've had a few months of experience towing with my V60 CC.
