Clarion vrx935vd dvd player, 2005 nissan altima

check your owners manual, maybe it mentions something about this. I know for sure that some vehicles have the stereo integrated into the security system so far that other functions of the vehicle wont work if the unit is unplugged. I can't remember which vehicles or where I saw that but I will try to find out. Look in your manual for sure to see what the alarm sections says about the LED flashing while disarmed and solid while armed.J Rilla

Did U use a Radio Interface or Hard wire it? Be sure you check and verify all of your connections.  I'm with auex...Put the Factory Radio back in. Take it to the Dealer and have the Codes removed or have them tell you what the problem is. Fix it first   Then use the correct InterfaceMO

Don't Learn from Others Mistakes

You Might Be the One That Knows.

I used the correct radio interface made sure of my connections, I just don't know.  I'm going to put the factory head unit back in and see if that changes anything.  I have an appointment with the dealer on tuesday so I have to get the new radio out and install the factory back.Joe Bennudriti

I know for certain cars you do need a antenna adapter.  Yeah I'm going to put the new radio in and use the I don't know face.  It's a great head unit.Joe Bennudriti
