Radio Screw Size - Bentley Disappointment

[BlackOnBlack]

What is the proper screw type and size to remove the radio. I've searched posts and help pages but none specify the type and size. I just purchased a Bentley for my '92 525im that I got in January but it doesn't state the type or size of the screw.
Can anyone help?

Hi Steve,
It takes a hex key to get the radio out, but my hex screws were too rounded off. Instead, I used a small flat-bladed precision screwdriver. It fit inside the hex head good enough to get the screws loose. You might try that.

bmw uses requires a tool with 5 sides , its a pentagon not a hexagon, some people use a allen wrench or hex key but each time you do that you take a chance on rounding it off and then really having a hard time. The bmw radio tools show up on ebay all the time and some people sell reground allen keys precisely ground to fit the five sided screw.

I have a set of small allen/hex keys - 1,1.5,2 - that I used. I managed to get mine out with, I think, the 2mm.

ditto, and it's real soft brass so it don't take much

I had started with a 2mm allen wrench and changed to a flat blade screwdriver but I fear that I may have started to strip them. I think I'll just buy one of the BMW tools...safer that way.
All I'm trying to do is replace 1 bulb in the radio and 2 in the OBC.

...the screws don't unscrew all the way. They push out little wedge blocks to hold the radio. Just back them off enough to loosen the radio. If you try to unscrew them all the way you break them. AMHIK

to change. My Babarian C professional RDS has no bulbs but 3 mm orange LED's. A very particular type, flat top, brilliant orange. I have never found them and used some similar orange units, but they light a little bit reddish.

Would like to know if his model is like mine, and found the original LED's.
