OK, I am putting my recommendation for this kit on hold. Whenever I'm using any device via the music connectors, Bluetooth audio streaming, or if I use the phone, my airbag warning light comes on and the indicators stop working (lord knows what else stops working). There must be some kind of interference. I have a support request into Parrot. I didn't go near anything or touch/remove/cut any wires installing the kit - it all just plugged in with the adaptor. I'm on the latest firmware too.
Will report back.
