I've got my car with an JDM aftermarket radio that i wanted to change to get the right radio frequencies and some other goodies. the radio was installed with a kind of module with which i just need to plug 2 sets of RCA. i dunno what brand it is. so! My radio is all wired up and works properly... BUT. it doesn't keep the settings.. like if the constant power wasn't working properly.. I remember that when i removed the old radio, some wires in the oem wiring where cutted and plugged differently.. I don't have a picture to show what i'm talking about but..
So, my question is, am i supposed to rewire something in the OEM wiring with a module like I have?
I can take a picture of what i'm talking about if needed.
Thanks for your help guys!
