In a vehicle, an authentication key may be transmitted by a mobile device to an automotive head unit over a first Bluetooth® link (securely-paired), then provided by the automotive head unit to a connectivity extension unit. The authentication key may also be transmitted by the mobile device to the connectivity extension unit over a second Bluetooth® link (not securely-paired). If the authentication key from the automotive head unit matches the authentication key from the mobile device, the connectivity extension unit may perform a transformation on the authentication key to generate a transformed key and transmit it to the mobile device over the second Bluetooth® link. The mobile device may perform the same transformation on its copy of the authentication key, and may compare the resulting transformed key to the transformed key from the connectivity extension unit. If the transformed keys match, the second Bluetooth® link may be verified as secure.
