I followed cn90's and a bunch of others and wrote it up for you here ...
(2002, BMW, 525i, Business CD, no DSP, no Nav, no CD changer, no tapedeck, no Sirius stellite radio, no bluetooth phone)
- Despite what other instructions say, I didn't need philips or torx screwdrivers.
- I only needed a 1.5 mm allen wrench & a 2 mm allen wrench
- 10mm box wrench (to disconnect & reconnect the battery)
Disconnect the battery:
- Open the trunk (you may wish to leave it open after disconnecting battery cables).
- With a 10 mm box or socket wrench, remove both battery cables, negative first.
Remove the MID unit:
- Cover the gear-shift knob with a soft towel to protect it and the equipment you're removing.
- With your fingers, pull the Multi-Information Display (MID) knob straight out & off.
- With a flashlight, locate the allen-head set screw at the 6 o'clock position just below serrated post.
- Insert a 1.5 mm Allen hex-head wrench & twist 90 degrees counterclockwise to retract the MID lock pin.
- With your hands, using light force, pull the MID unit straight out away from the dashboard.
- Disconnect the MID data-input cable (press the fancy Molex-connector lever & flip it's handle 90 degrees).
- Place the MID unit in a safe place (e.g., on a towel strategically placed across the back seat).
Remove the Business CD & radio combination unit:
- Twist the two 2 mm allen head clamp-adjust screws under the Business CD just until they spin freely.
- With your hands, using light force, pull the Business CD straight out away from the dash.
- Unclip the small black radio aerial connector by depressing the raised ridge with your fingers and pulling straight out.
- Unclip the very large radio-cable harness by depressing a small tab inside the black lever then opening the lever upwards.
- Pull the radio-cable harness connector straight out, away from the Business CD unit.
- Place the radio in a safe place (e.g., on a towel placed across the back seat).
