I like the unit, it adds some much needed capabilities to my car.
Some things I would like:
1. Wiring and installation instructions could be clearer. I used a few YouTube videos to install.
2. Post install, the interface could benefit from some flexibility in design. There were a few components in the tab that I do not need and had to spend time uninstalling/ removing.
3. Customization: I had to experiment with a few things to get them working as I want them.
