Choo Choo Customs used Audiovox, Code Alarm because they convinced the big three to endorse their names right on the alarm box, Motorcraft, Goodwrench and Mopar. Directed Electronics was the only thing I installed at Best Buy, Viper, Python, Clifford, Avital. Avital let me down last year when our F250 was broke into. So I switched back to an Audiovox APS997N two way paging, we also have The Snitch, a Realtime GPS Tracking device.
I just did the basic options for now......even that was a lot of green I work at Best Buy in the Geek Squad
I think it runs about $699 installed......good investment I say Oh and having it started with the AC cranked in this heat wave we're having...BA!!!!
