BMW Assist
From Wikipedia, the free encyclopedia
[edit] Overview
BMW Assist is a cellular based automotive roadside assistance service offered by BMW. BMW Assist is similar GM's OnStar or Mercedes-Benz MAYDAY services as they both use the cellular network and Global Positioning telemetry to locate or guide the vehicle. BMW Assist can provide turn-by-turn directions, vehicle diagnostics, airbag deployment notification, theft recovery and towing or flat tire repair. The service is included free in most new BMW's. After expiration, it can be purchased at a yearly rate.
[edit] Technology
BMW Assist is integrated into the cars communication and audio systems. It works in conjunction with the navigation system (if equipped) or uses its own GPS equipment. The original BMW Assist system worked in conjunction with the AMPS cellular network for data transmission and voice communication. Current BMW Assist systems work using more advanced CDMA, TDMA, or GSM technology.
