Do these cameras use the existing screen on the rec radio? If not does such a thing exist?
2007 Ram 3500 Mega Cab with REC radio.

 

Whats a REC radio? May want to try asking in the Ram Section. You are in the Dakota forums.

 

Mine doesn't as my truck doesn't have the connection for the factory nav. I believe it's either after 2005 or maybe the lariame that has this option.

 

To unlock the feature on a REC system for a backup camera you would need to purchase a Lockpick system. Something like this: http://www.coastaletech.com/REC_LOCKPICK.htm

I recommend doing some research over at mofv.com website: http://mofv.com/mygig/

Good Luck.

 

Thanks for all the help. For clay REC is the option code for my nav radio. I am going to purchase the lock pic and two cameras so I can see behind and watch as I hook up the 5th wheel. Thanks again:-) :-) :-) :-)

 

Ahhh. I've got the lock pick and back up. Am on my wife's 2008 Dakota. Don't remember the code but it works with pretty much any dodge radio with a screen. Has tons of options. Got the one that works with iPhone as well. Don't really use that option much though.
