Anti-thef t Featur e
Th e navigatio n syste m ha s a code d thef t protectio n circuit . B e sur e t o ge t th e customer' s four-digi t securit y cod e numbe r
before ;
• disconnectin g th e batter y
• disconnectin g th e navigatio n uni t connecto r
• removin g th e BACK-UP/RADI O (7. 5 A ) fus e fro m th e under-hoo d fuse/rela y bo x
Afte r service , reconnec t powe r t o th e navigatio n unit , an d tur n th e ignitio n switc h O N (II) . Ente r th e 4-digi t securit y code ,
then selec t "Done" . Whe n replacin g th e navigatio n unit , b e sur e to giv e th e custome r th e ne w anti-thef t securit y code .
Sympto m Diagnosi s
Certain circumstance s an d syste m limitation s wil l produc e occasiona l vehicl e positionin g errors . Som e customer s ma y

Self-lnertia l Navigatio n Limitation s
Th e limitation s o f th e self-inertia l portio n o f th e navigatio n syste m (th e ya w rat e senso r an d th e vehicl e spee d sensor ) can
caus e som e discrepancie s betwee n th e actua l vehicl e positio n an d th e indicate d vehicl e position . I f ther e i s a larg e dis -
crepancy , an d th e syste m is receivin g GP S signals , th e syste m wil l adjus t th e indicate d vehicl e positio n to th e GP S vehicl e
position . However , i f GP S signal s canno t b e received , yo u mus t tun e th e vehicl e positio n manually .

Troubleshooting Precaution s (cont'd )
Global Positionin g Syste m (GPS ) Limitation s
Th e GP S canno t detec t th e vehicl e positio n in thes e instances :
Fo r th e firs t 5 to 1 0 minute s afte r reconnectin g th e battery .
Whe n th e satellit e signal s ar e blocke d b y tal l building , mountains , tunnels , larg e trees , o r larg e trucks .

Whe n th e satellit e signal s ar e blocke d b y th e operatio n o f som e electroni c aftermarke t accessories .
Th e precisio n o f th e GP S is reduce d in thes e instances :
• Whe n onl y tw o satellit e signal s ca n b e received . (Thre e satellit e signal s ar e require d fo r accurat e positioning. )
• Whe n th e satellit e contro l cente r purposel y lower s th e signa l precision .
LC D Displa y Uni t Limitation s
• I n col d temperatures , th e displa y ma y sta y dar k fo r th e firs t 2 o r 3 minute s unti l i t warm s up .
