If anyone does get one, make sure you get the BC30 complete kit (https://buy.garmin.com/en-GB/GB/p/501486) as you can also buy an additional camera which is usually around £95. However, the full kit comes with a replacement power cable for your existing Garmin sat nav that includes the receiver for the camera, the additional camera doesn't come with this as the system can have up to 4 cameras tied to the one sat nav.
