HU service manual and schematics

[ToVreB]

Hi, I've contacted both BMW and Alpine service organisations here in Norway, none of these are able to supply schematics (service manual) for the Head Unit installed in Mini's. I would like to have this due to some modifications. I've seen the connector pinout, this may be a copy of a service manual? Would love to see the rest of it...
My CD-player is Alpine type CD53 R50.
Are anyone able to obtain this manual?
Regards, Tore

I think it was GaryM that got the boost head unit pin out that you are talking about. That's all he got just the pin out.

If you are looking to get some RCA low level out GaryM already done it. thread here

Thanks, I've seen that info from GaryM. He also helped me in the starting of my modification plans.
I'm thinking of using the nav/TV inputs for voice guidance from my iPAQ with TomTom software. I'll have to figure out how this is working...
Does the HU automatically mute existing audio when voice is detected on the inputs? A separate trigger line? Many questions...
Regards, Tore

ToreB,

Any luck? Im looking to do the same with my Ipaq. From a phone install manual I can see that pin 10 is mute. I'd really like to get my Ipaq hooked up to the NAV input though

No luck, sold my Mini. Sorry...
