I have successfully paired the BT3 with my iPhone 6s and it works well most of the time. However, every few days the BT3 and my phone will not connect and I have to go though the reset procedure and re-pair the Grom with the phone. From your FAQ it seems that this is caused by the BTD entering "corrupt mode" (see below). Please help to fix this issue.
"BTD module may go into corrupt mode. Do the following sequence:
1. Enable mode switching state (GROM-FM-GROM)
2. Immediately press SCAN button few times
3. There should be two voice beeps confirming full reset
You should be able to select and connect to GROM-CAR now"
