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 "ISO" 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, but these might be unpopulated.


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.

Connectors

The OEM wiring harness of the Crossfire consists of:

  • 2 connectors from ISO-10487 ("A" and "B")
    • Connector "B" only has wires for the "front" speakers. You cannot use the OEM harness for controlling the rear speakers, which has to be modified manually through the 4-Channel upgrade explained below.
  • 1 FM antenna connector, ISO for NAV version, and probably DIN or FAKRA for non-NAV version.
  • [only NAV] 1 male SMA antenna connector for the active GPS


FM Antenna

The roadster is fitted with an external antenna, similar to Volkswagen. Google P/N 1J0035849F. There is also a shorter version of the antenna, which you can find by googling "9 inch antenna volkswagen 2004".

The coupe has the antenna integrated in the rear window heating array, and is powered by the "Antenna ON" signal of the headunit (connector A pin 5). This antenna module is a Chrysler part. Note: if you have issues with your amplifier and/or FM radio reception, there is a chance that the cabling in the sleeve going into the rear hatch is being cut through the metal, shorting the ON signal to the chassis (common issue in cars).

GPS Antenna

This antenna is located [figure out where, probably in front of car], and is a Wisi AG 13, an active GPS antenna with a male SMA connector. There is a thread on the Crossfire Forum that explains a lot.

Part numbers

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

4-channel configuration

As shown above, the amplifier does have 4 channels. However, the B connector on the Becker radio only wires the Front channels. Amplifier wiring.png


It is possible to pull 4 new wires for the rear speakers to the headunit, by cutting the following wires on the Power Amplifier A connector: 10 (RR+, yellow) 9 (RR-, yellow/violet) 8 (RL+, blue) 3 (RL-, blue/brown). Then, wire these to the radio on either RCA jacks or into the Radio B connector using "ISO radio connector pins".
