We install several of these units. It is our preferred unit to install into customers vehicles due to no issues after install. As a shop we don't want customers coming back and having to uninstall and reinstall their product. With dc3 and drone mobile we don't have to worry about that issue. It says 1 yr warranty but we haven't had a unit come back yet for as a faulty unit. Compustar makes our customers happy which makes us happy as installers.
