If you have a Tahoe, BMW, Mercedes or other vehicle that isn’t pairing over Bluetooth with your new iPhone 6 or iPhone 6 plus, there’s a workaround I found that can get them connected.
1. On your iPhone, go to SETTINGS – GENERAL – ABOUT – NAME.
2. Rename your iPhone something equal to 8 characters. Try your initials + “iPhone” (for example: REiphone).
3. Back out of that area by pressing ABOUT – GENERAL – SETTINGS
Now try pairing your iPhone with your vehicle. It should work fine now.
