Reverse Camera - best option?
 

I have an '04 4.4i with NAV, and am wanting to add a reversing camera to the vehicle. I understand the OEM BMW kit is no longer available -- what are other good options? Important is the ability for this thing to "automatically" go to camera mode when the vehicle is put into reverse. The TVonNAV solution looks like I'd need to toggle the nav screen manually. Thoughts and opinions appreciated!

Thanks,
Matt

With a relay installed it will automatically display the reverse camera. There is no need to toggle anything on the NAV. This is true with TVonNav camera or any reverse camera wired with a relay from one of the backup lights. Here is TVonNav's schematic

In order to have the backup cam you'll either need to have the BMW TV module installed (which you will have with the TVonNav system) or you can go with this solution - http://www.xoutpost.com/articles.php?...ticle&artid=24
