Not true on the belt temp... the one button gauge on my 2020.5 turbo had no issue displaying... it was just one click past engine temp.You are not able to control the hand warmers and you are not able to see belt temp on the old gauge ?.
No, that's like saying if you snow checked a snowmobile and got a snow blower!Remember that next time you are at a restaurant and order a steak and when they bring you a hamburger patty with steak spice and charge you for the steak its not worth any drama just be happy you paid for a meal
