Aftermarket backup camera for 2015 CLA250?

Greetings,

I've done a little checking on the issue below, but I haven't had any luck finding a definitive answer.

Is there an aftermarket backup camera available to be installed on a 2015 CLA250, which could make use of the OEM installed screen? The price for the factory package that included a backup camera was outrageous, so I'm looking to add this on of possible.

Thanks.
