Metra 70-7550 vs 70-7551. Which one do I need?
I have a 2004 w/ Bose & no navi and am getting ready to do a DD install myself. I am confused as to which on of these I need. I have searched through the forums & what I found is some people have used either. Also, Crutchfield says I need this

which looks like the Metra 70-7550. Please advise on which one I need for my setup.

^ not necessarily - it depends on the preout voltage of the deck.
if you have 4volt or higher preout use the 7551 if it's <4 volts use 7550. Overall, there is 0 chance you will get engine noise from the deck if you use 7550 harness and maybe a 25% chance of getting engine noise with the 7551.
Engine noise refers to changing ONLY the deck in this case.
