I have installed the same dc3 into 3 of my vehicles. It has flashed and worked flawlessly in each vehicle. I always add on the drone mobile and security add on. I have been in love with compustar since I first started installing them. They work flawlessly from the beginning. Not something I can say for other manufacturers. As Compustar grows, I hope to add more accessories to my personal vehicle. When it comes to recommendations for what system I should install in to client vehicles, it is ALWAYS Compustar!
