I haven't yet had a chance to ride with the CB I bought but I did do a MacGuyver on the cheap rubber mount. Pulled out the hard plastic bit with its brass threaded insert, cobbled up a Cestbon bayonet-type aluminum+plastic Garmin mount so the 5mm FH machine screw works with the CB attachment clip. Much more solid mounting to my seat Selle Royale seat's rails that hung from a rubber band off the seat post below.
Sunday's supposed to be 78°F here, sunny with some SW wind gusts to 24 mph so I fully expect to be riding once again for this year! Will report on whether the CB adds to the experience.
Red side shading on my Garmin and an audible alarm warning when a vehicle is bearing down fast. Orange shading and a more subtle audio beep for slower vehicles. Maybe Trek will add something similar in future updates. But I expect you will find your CB useful. I would really miss having that rear traffic awareness now. I ride mostly in rural locations where it is invaluable, especially on descents when wind noise is high and I don't want to be looking over my shoulder.
