Sorry for the late reply...like mingo, I rented a '23 GT+ on an Edelweiss tour, the Saint James Way. (On an earlier Edelweiss tour, I rode a Tracer 900GT and then traded in my FJ-09 for a new Tracer 900GT).
I had some trouble with the GT+ rental; it was stuck in Rain mode until eventually the Mode button started working (the Machine Settings stayed greyed out most of the time). Connecting my phone to the TFT was fussy, but it eventually worked. Everything else on the bike worked great.
Back in the States, I rode a demo unit at Barber's and that sealed the deal.
I kept watch on Cycle Trader and I could see Yamaha was shipping the bikes to dealers. I struck a deal with my local dealer and got a decent trade-in on the 900GT. COVID-era sales and negotiations are over. Heck, there was even a T7 on the floor for sale!
I have only 600 miles on the bike so far. TFT, phone, and helmet config was a breeze. The Yamaha top box platform for the rack doesn't seem to be available anywhere.
