Re: car stereo install questions

["Ron Buchalski" <rbuchals@xxxxxxxxxxx>]

Mike,

I installed an Alpine in-dash CD player in my '93 E34 525iT.  In order to 
install an aftermarket radio into a BMW, you just need to purchase a wiring 
adapter that will plug into the factory radio connector, and allow you to 
connect/solder the wiring adapter that hooks to your Blaupunkt.  So, you get 
something like this:

FACTORY   AFTERMARKET    BLAUPUNKT
RADIO     ADAPTER        WIRING
CONN                     HARNESS
                                -----------
       ---  ---  <splice>  --- |           |
      |   ||   |----//----|   || BLAUPUNKT |
      |   ||   |----//----|   ||   RADIO   |
      |   ||   |----//----|   ||           |
       ---  ---            --- |           |
                                -----------

I also needed an antenna wire adapter, since my Alpine has the standard (US) 
antenna wire jack, but the E34 has a smaller Euro antenna wire.

Connecting the aftermarket adapter to the radio's wire harness is very easy. 
  You just match up Power, Ground, Speaker wires (LF + -, RF + -, LR + -, RR 
+ -, memory power, power antenna (my 525iT has an window antenna, so this 
wasn't needed).

That should do it.

I purchased my adapter from East Coast Auto Sound in Rockville, but they're 
no longer in business.  You can probably get the adapter from Crutchfield.

Whatever you do, don't cut off the factory connector.
