“Just recently had BBY installed my Compustar 4905s unit and regret not adding the alarm system. Are these unit plug and play or do they need to be software activated at the module?”

• I am not sure. However, I suggest to purchase Best Buy’s Total Tech. If you do so, the installation should be free. For me having several vehicles in the family, it really pays for itself. Plus the assurance the installation is done professionally and correctly. If I have any issues I can take the vehicle back to Best Buy.
