Adding Beeper Sound to Backup Camera Question

Has anyone add beepers to their existing backup camera? My wife had them on her previous car and prefers to hear the rapid beeping warning sound when something is behind the vehicle. She likes the one that Ford has on my 2008 Expedition (no sensors on the bumper) but is open to the option of having bumper sensors.

Thanks,

I have had two customers purchase the Park Distance Control from me recently. I do not know their TDIClub user name and I haven't seen them post a thread about it.

But If you search you may be able to find something.

For reference, Here is the system they bought:
