Abstract: A system and apparatus for limiting use of mobile communication devices which utilizes vehicle diagnostic information transmitted via the Bluetooth™ communications protocol to a mobile device (PDA, cell phone, laptop, portable printer, GPS, iPod, etc.). If the vehicle diagnostic data meets predetermined criteria, the software configured to evaluate vehicle diagnostic data selectively authorizes telephone calls, incoming text messages, incoming pager messages, incoming e-mails, outgoing telephone calls, outgoing text messages, etc. If the predetermined criteria are not met, the functionality of mobile communication devices will be limited.
