The High Li ne Audi o s yst em is bas ed around an Integrat ed Audio Module (IAM) which communicates on the Medi aOrientat ed Sys t em Trans port (MOST). The ICM communicat es on medium speed CAN and MOST buses .
The IAM cont ains t he fol lowi ng functi onali ty:
Radio t unerCD pl ayer (Si ngle CD or Si x dis c i n dash changer)Auxi li ary i nput (for any device feat uring a 3.5mm jack pl ug out put).
The ICM is woken up by CAN bus acti vi ty. The IAM i s woken up by the MOST ri ng.
The ICM is the Bus Mas t er for the MOST s ys t em and contai ns the t iming mas t er for the MOST s ys t em.
TUNER
The IAM incorporat es a AM/FM t uner whi ch al lows for 30 FM pre-s ets (FM1 FM2 FM a) and 20 AM (10 AM and 10 AM a, forEurope t he 10 s tronges t LW and MW wil l be st ored in frequency order). Pre-s et s tat ions are st ored i n t he IAM and ICMmemory. The radio t uner al so incorporat es the foll owi ng radi o functi ons :

• NOTE: On vehicles fit t ed wit h t he HD radio module, t he module replaces the AM/FM funct ion i n t he IAM. AM and FMantennae are connect ed direct ly i nto the HD radio module and not int o t he IAM; therefore t he AM/FM functi ons in the IAM

The HD radi o module recei ves the analogue and digi tal s ignals vi a thevehi cl e AM and FM antennae along wi th accompanyi ng text t ransmis s ions. Thes e s ignals are decoded by t he module andplayed as an audio out put or di spl ayed as an informati on text on t he head unit LCD dis play or t he ICM LCD di spl aydepending the s ys tem ins tal led.
The HD radio modul e is locat ed in the LH s ide of t he luggage compartment . The modul e receives a fus ed power s upplyfrom the AJB. The modul e i s als o connected on the MOST ri ng and is abl e t o communicate wit h the ot her ent ert ainmentand informat ion s ys tems i n t he vehi cl e.
CLOCK

Des cript ion and Operat ion
OVERVIEW
A number of different t ypes of communicati on network are incorporated into the vehicle wiring harnes s es for t het ransmis s ion of commands and informat ion between control modul es. The confi gurati on ins tal led on a parti cul ar vehicl edepends on t he model and equi pment level .
The communicati on net works avail abl e on t he vehi cl e are:

LOCAL INTERCONNECT NETWORK BUS
The Local Int erconnect Network (LIN) bus is a low s peed broadcas t net work that employs mas ter and s lave component s .The mas ter component t rans mit s a mess age along a si ngle wi re to the s lave component s i dent ifyi ng which s lave i s t ores pond. The mes s age has a header (s lave ident ifi er) and an empt y data fi eld. The identi fi ed s lave component fi ll s thedata fiel d wi th t he relevant i nformat ion and ret urns a mes s age to the mast er component along t he s ame wire.
CONTROLLER AREA NETWORK BUS
The Control ler Area Network (CAN) bus i s a high speed broadcast net work where cont rol modules aut omat icall y t rans mitinformat ion every few micros econds . Informati on is broadcas t down a pair of t wis t ed wires, known as 'CAN high' and 'CANlow'. Informat ion i s transmit ted on t he CAN bus as a vol tage di fference bet ween t he 2 wi res .
Two CAN bus net works are used on the vehicle; medi um s peed and high s peed, wi th the Cent ral Juncti on Box (CJB) acti ngas a gat eway bet ween t he 2 networks . The t abl e below shows t he wi re colors us ed on both net works .
