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:

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).

• 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

are di s abl ed.
CD PLAYER
The IAM CD pl ayer i s a 6 di sc mult i changer l ocat ed in the center of t he ins trument panel. The CD mult i changer is capabl eof playing commerci al CDs , CDRs , CDRW s and MP3 di scs .
Random Play
The random pl ay feat ure works in t wo di fferent ways :
Random play of t racks on a CDRandom play of all t racks on any CD i n t he autochanger
The s ingle di s c random feat ure plays all t he tracks on t he s elected CD in a random order. All t he t racks on that dis c wi ll beplayed before a new random s equence is pl ayed. If a new CD is s elected whi le in random mode, the random mode wi ll becancell ed and play wi ll commence from t he fi rs t t rack.
In mult i dis c mode t he IAM us es the current track as the firs t random t rack and wi ll t hen pl ay a furt her 2 tracks (ifavai lable) from thi s CD. The IAM wil l then randoml y s elect anot her CD, and pl ay 3 random tracks . Thi s s equence cont inuesunti l al l tracks from all CD's are played back.

Automatic Volume Control (AVC)
AVC control s t he audi o volume in relati on t o vehi cl e s peed. As vehicle speed i ncreases t he audi o l evel is adjust ed t ocompens ate for extra road and vehicle noi s e. There are 4 s et t ings for AVC:

The default s ett ing is medi um.
Changi ng the AVC level is acces s ed by a l ong pres s of the TONE but t on and sel ect ion of t he AVC us ing t he rot ary encodert o change t he level.
The vehi cl e s peed s ignal i s us ed to enable the ICM to calculat e t he vol ume adjus t ment required. The vehicle s peed s ignalis recei ved over t he medium s peed CAN. The s ignal is an average of t he four wheel s peed s ens or s i gnal s. Should an inval ids peed si gnal be recei ved t he AVC will not alt er the out put volume.
AVC i s cont rol led by t he audi o ampl ifi er.
CD Error Messages
W hen an CD error occurs , the IAM wil l al ert t he us er by s howing a dis play related to t he error. This wil l be dis played whilet he CD audio mode is s elected unt il t he error is correct ed. The CD rel at ed error does not affect other areas of t he IAM. Theus er i s able t o s elect a di fferent audi o s ource.

HIGH DEFINITION (HD) RADIO - From 2009MY (NAS Only)
HD radio i s t he regis t ered t rademark for t he In-Band On-Channel (IBOC) t echnology s elected by the FederalCommunicati ons Commis s ion (FCC) for t erres t ri al di gi tal audio broadcast ing in t he Unit ed St at es . A large number of radi os tat ions now broadcast i n both AM and FM. FM frequenci es are capabl e of t rans mit ti ng mult ipl e frequency s treams on as ingle FM frequency. HD radi o has an advant age over SDARS in that i t is free t o recei ve and requires no s ubs cri pt ion.
HD radio enhances t he s ound qual it y of the recei ved si gnal s o t hat FM recepti on gives near CD qual it y digit al reproducti onand AM recept ion s ounds as ri ch as anal og FM s tereo. Bot h AM and FM HD radio offer stat ic-free, crys tal -clear recepti on. Anaddi ti onal benefi t is FM Mult icas t ing – the abi lit y t o broadcas t mul ti ple program s treams over a s ingle FM frequency (forexampl e 97.7-1, 97.7-2, etc.).

The HD radio modul e replaces t he AM/FM functi on in t he IAM. AM and FM ant ennae are connected di rectl y i nt o t he HD radiomodule and not i nt o t he IAM; therefore the AM/FM funct ions in the IAM are dis abled.
