I bought this with intent to use on a plane. But seems there is no screen so how to pair a BT headset to the planes audio?

Hi friend, This is a 5.3 aux Bluetooth receiver that is used to pair with Bluetooth devices such as your phone/tablet. It does not work with Bluetooth headsets. You can refer to the steps of " How to pair Bluetooth" in the Product description on our page. Hope it helps.

Can these bluetooth devices be renamed? if i bought 2 of them could i name one "kitchen" and one "basement"?

Hi friend, You can rename the car aux Bluetooth adapter on your phone if your phone supports this function. But the name is only available on the phone you use. Hope it helps.

What is the maximum temperature allowed for this device? Can I leave it in the car under the sun?

Hi friend, The suggested storage temperature of this Aux Bluetooth adapter is 14F~122F. Hope it helps.
