I have a 2007 Tucson SE , wanting to look into upgrading the radio to a more modern one , maybe even with nav and backup camera ???

 

Make sure you do as much homework on this one.as you can.
Because ,,, from 2008 and on, some vehicles have adopted the "Controller Area Network" system and the radio is one of the modules in the network on some systems and a lot will depend on whose radio you install etc.

 

Were you able to get to install a more current radio?
