So my local dealer is saying the TFT display is necessary to install the sofware update for the hill start feature. I believe the TFT is the newer dash on the 2018 model. I have read some posts on the adv rider that imply it can be installed on the older bikes without the newer TFT dash. I'm not sure my local dealer is really that motivated. has anyone tried this? I have a 2017 GSA and my sole interest is to hold the bike on a hill while releasing the brake.
