How do I see if my Matrix/BlueBox is compatible to receive GSM calls?
To determine your current software, navigate to the main menu and press HANG UP three times to enter the hidden menu and choose REV. GSM operation requires Module 7.0 or higher; and Matrix Control software 8.0 or higher or BlueBox Control software 2.0 or higher. Control software can be downloaded online. If you have an earlier Matrix revision, contact Tech Support for more information.
