This Curt from Amazon. I bought it because it just holds up bikes, it doesn't have to be fancy. I got it with Prime shipping in 2 days. I installed it with a friend in 15 minutes. You have to drop the exhaust temporarily, but there's no cutting or other BS required.
The Kuat Transfer doesn't block the rear camera much, even when folded up. With 2 bikes on it, you can't see much, but it's still better than no backup camera. I just used my Mk7 as the SAG vehicle at my bike team training camp, and it did great.
Yes Curt sells a hitch for the Mk7. That's what I've got and a hitch rack. It works great and was easy to install.

That's the one I got from Amazon. Plus a Prorack which I don't see listed anymore.
From that same site, I don’t believe it was on any special sale at the time. Here it is on amazon for 125
CURT 11412 Class 1 Trailer Hitch, 1-1/4-Inch Receiver, Select Volkswagen Golf, GTI,Black https://www.amazon.com/dp/B0133WU3K8/ref=cm_sw_r_cp_api_i_mEq7EbMH691JE
Really easy to install. If you search on YouTube there is an easy tutorial video. Might just need an extra set of hands to hold it while installing but I just used a jack
Hitches are the way to go! Im currently using the Curt 11412 hitch on my '19 gti. I had a curt hitch on my veloster and it served me well. Amazon will state this will not fit on the '19 gti's but i confirmed on curt's site that i will in fact fit. Installed without any issues!

NWheelspin & water_power20 are spot on. It is a straight forward, fairly simple install, especially if you have access to ramps/lift & the right tools. But if you don't, I called a few local shops (NE WI), and was quoted around $80. And the Curt Hitch (114112) is actually on sale for $125 right now on Amazon (I know Amazon says this hitch does not fit the GTI, but this is the exact one I purchased & installed. Read the reviews too, many GTI owners state it fits). Check out the links below!
