    Radio question

    I need a radio pinout diagram or list. I have a dvd/nav radio out of a newer escalade and do not have a wiring harness for it. I don't know if it works and don't want to wast my money on a harness if it doesn't work. The radio is gm pn: 15896129 and it says supernav on it. Delphi ph: 28059049
    I just want to test it before I do anything with it. Anyhelp would be muchly appreciated.

    Re: Radio question

    I am not sure what you are asking, but you can't just wire it up to a battery to check it, you'll have to plug it into a vehicle in order to power it up.
    The radio is turned on by a computer data signal, not a switched power input.
    It has to get that signal from another computer, also it will be in theftlock mode if it can't retrieve a valid matching VIN from the data bus of whatever vehicle it is plugged into.

    Re: Radio question

    I need to know which is the power for it and which is the data signal for it. My friend can send the signal to it from a program he has to get it to power up i just need to know the hookups for it and the rest of it for that matter. If i can't get it to work im gonna pull it apart for parts anyways.

    I am mainly just looking for the little digram that comes with a wiring harness when you buy it(for lack of better words).

    Thanks

    Re: Radio question

    PM me your email addy and I'll see if I can dig up some connector views.
    I don't think they will do you any good, but I don't mind trying to help at least that much.
    I need the year also.
    All the supernavs are U3R I think. I could be mixing that up with another model but I am pretty sure....

    U3R is my RPO Nav
    U3R U3S and U3Q are the Denso navs
    Lade uses Delphi i believe
