The unit works incredibly well and is relatively easy to install if you’re a beginner with self car work. The customer service, I’d give 10 stars if I could. There was an issue and I quite honestly have never seen a seller or company care so much to resolve a situation and it took awhile. Don’t be nervous about this unit it will work well juts follow the instructions they give. If you have any issue at all or questions they will absolutely help you. 🌟 💫
