Replacing radio 77 240d

[DCM]

I want to replace the radio in my old 240d because it is fading out under bridges etc and I have never liked the controls.

A while back, I read the instructions on a Blaupunckt radio with CD player and it mentioned having to install a strap on the firewall inside the console to stabilize the CD player.

I have pulled out my old radio a couple of times so can see the available space for the new radio.

There is no way my hands will fit in there so was wondering how important that strap really is. Is there an alternative location for such a strap or an easy way to open up more space in that console for the installation? Thanks
