The crossfire is fitted with a Becker radio, based on the Becker DTM High Speed. The speakers on the non-Base models are powered by an additional Infinity Amplifier.

Radio

MOST/D2B yellow connection cap

The radio itself seems to be based on the Becker Monza, and has all 3 connectors (A, B, C), although connector C is not used. Another spot for a MOST/D2B (Mercedes) connection can be found, but no fiber optics are installed (sometimes).

Some models do seem to include a MOST/D2B connection, as shown below.


The NAV model has an additional C/C button, that is used for the CD Changer, a function that was never shipped with the crossfire. You can find documentation about the CD changer and installation here : https://www.crossfireforum.org/forum/audio-video-electronics/10953-cd-changer-nav-receivers.html . However, there are other variants that have a DTM button instead.

Part numbers

The Becker "ZH 29" type might refer to the Chrysler naming of the Coupe model, ZH29.
