Introduction:
Safety comes first when you’re on the road, so having an intuitive and easy to
use Bluetooth kit is essential to reducing driver distraction. The new BT45-BKR
kit is compatible with virtually all Bluetooth phones, and sounds great whether
using it for mobile conversations or streaming music. The wireless remote
control button conveniently installed on the dash is used to launch Voice
Recognition application (Siri, Google Now, Assistant etc.) initiate phone calls and
launch important applications. Thanks to the BT45-BKR Kit you can keep the
radio and car you love while enjoying Bluetooth features only available on
newer cars.

without the code. Do not proceed to step 4 if radio code
is not available otherwise radio will not operate upon
reconnection.
