This is the mod that automatically selects the PWR mode after starting your Prius, without having to press it. Supposedly this only works on the 2010 & 2011 Gen 3 Prius, per cproaudio, who made this. I never attempted to install this on my 2014 Prius, because I read that others found it doesn't work on 2012+ models. Asking $100 (Paypal). I'll ship for free using USPS Priority mail within the U.S. or local pickup in DFW, Texas. You can read more about it here: Default PWR mode | PriusChat
