High-Line In-Car Entertainment Description
The high-line in-car entertainment system consists of a head unit, located in the center of the fascia, a power amplifier located under the LH front seat and a CD autochanger located under the RH front seat. Radio headphone amplifiers are located in the lower rear quarter trim casing. Remote controls are located on the LH side of the steering wheel. The high line system has:
^ A high range speaker located in each A post trim
^ A low and mid range speaker located in the front doors
^ A low and a high range speaker located in the rear doors
^ Low range speakers located in a housing on the tail door
^ An AM/FM aerial mounted on the RH rear side window and an FM aerial mounted on the LH side window. The LH aerial is used for improved FM reception in urban areas
The system can be controlled from the head unit, the remote controls on the steering wheel, or the radio headphone amplifiers. The driver's selection via the head unit or remote controls has priority over the radio headphone amplifier's control selections.
In-Car Entertainment (ICE) High-Line System Supply
Circuit supply
A permanent feed from the battery positive terminal is connected by an R wire to the engine compartment fusebox, where it passes through fusible link 3 From fusible link 3 the feed passes on an NR wire to fuse 20 in the passenger compartment fusebox. From fuse 20 the feed flows on a P wire via header C0725 to the head unit. This feed supplies power to the internal memory and the power switch on the head unit.
A feed for illumination passes through fusible link 13 in the engine compartment fusebox and on an NG wire to the lighting switch. From the lighting switch the feed passes on an R wire to fuse 33 in the passenger compartment fusebox. The feed from fuse 33 is connected to header C0759 by an RO wire. After passing through two links on header C0759, one on an RO wire and one on an RN wire, the feed is connected to the head unit on an RN wire.
The permanent feed to the engine compartment fusebox is also connected in series through fusible links 1 and 7. From fusible link 7 the feed is connected to the contacts of the auxiliary circuits relay.
A permanent feed from fusible link 7 in the engine compartment fusebox is connected to fuse 17 in the passenger compartment fusebox on a PG wire. From fuse 17 the feed is connected to the power amplifier by a LGP wire.
NOTE: This feed is operational when enabled by a signal from the head unit.
Another connection inside the engine compartment fusebox connects fusible link 8 to the permanent supply. From fusible link 8 the feed is connected to the passenger compartment fusebox on an NW wire. From the passenger compartment fusebox the feed flows to the ignition switch on an N wire.
Ignition switch supply
When the ignition switch is in position II, the feed from fusible link 8 in the engine compartment fusebox flows on an LGW wire to fuse 26 in the passenger compartment fusebox.
From fuse 26 the feed is connected on an LG wire to the coil of the auxiliary circuits relay. The coil of the auxiliary circuits relay is earthed via header C0286 LHD/C0288 RHD to earth header C0018 on a B wire.
When the ignition switch is in position II, the coil of the auxiliary relay is energised closing the relay contacts.
The feed from the contacts of the auxiliary relay flows on a WG wire to fuse 16 in the passenger compartment fusebox. From fuse 16 a feed on an LGO wire flows to header C0296. From header C0296 the feed flows on a LGO wire to the LH and RH radio headphone amplifiers.
NOTE: This feed is operational when enabled by a signal from the head unit.
Another feed from fuse 16 in the passenger compartment fusebox is connected via splice joint A7 to the head unit on an LGP wire. This feed supplies the power to the head unit On/Off switch and glowring illumination.
A feed from the head unit is connected via header C0285 LHD/ C0761 RHD to the power amplifier and header C0296 on RU wires. From header C0296 RU wires connect the feed to the LH and RH aerial amplifiers, and the LH and RH radio headphone amplifiers.
NOTE: This feed is the power supply to the aerial amplifiers and forms the system enable output from the head unit to the radio headphone amplifiers and the power amplifier. This feed is on as long as the head unit is switched on.
