Hello and thanks for reaching out!
We apologize for the frustration. You may want to try a soft reset by removing the battery, waiting at least 2 minutes, replacing the battery, and rebooting the device. Also, check with your vehicle manufacturer to ensure that it has the Bluetooth profiles that are compatible with your device.
If you need additional assistance please contact us again. You can also reach out to us via twitter or facebook for quicker responses.
Thank you and have a great day!
