I used this on a Fit Shuttle Hybrid (Fit 2). I understand it's compatible with Fit Hybrids and Fit Shuttle Hybrids from around 2011 to 2015. This is a rare model that's hard to find these days. It comes with an immobilizer adapter that cost around 15,000 yen at the time, so it can be installed directly. It may also be compatible with non-hybrid models, so please research it yourself. The starter model is: ・Mituba Sankowa HX-10M
