Mounting & Wiring
Please read entire manual before installation.
Before You Start
• Disconnectnegativebatteryterminal.Consultaqualifiedtechnicianforinstructions.
• Avoidinstallingtheunitwhereitwouldbesubjecttohightemperatures,suchasfrom
directsunlight,orwhereitwouldbesubjecttodust,dirtorexcessivevibration.
Getting Started
• Onceasuitablelocationhasbeendetermined,drilltheholeandsecurethestereo
usingthemetalmountingbracket.Ifthebracketneedstobeshortened,removethe
appropriatenumberofbreakawaysegmentsusingapairofpliers.
Fuse:
Whenreplacingthefuse,makesure
newfuseisthecorrecttypeand
amperage.Usinganincorrectfuse
coulddamagetheradio.
Tip:
Whenasuitablegroundwireis

Mounting the Radio
1. Chooseamountinglocationonthedashboardorinstrumentpanelthatwill
allowroombehindtorunradiocablestothepowersource.Considerhowyouwilluse
theAUXIN,LINEOUTandUSBconnectorsandroutetheappropriateextensioncables
toanaccessiblearea.
2. Cutaholeinthedashboardusingthetemplateprovidedinthebackofthismanual.At
least33/4”depthisneededtomounttheradio.
IMPORTANT! Do not mount this unit where it can be submerged in water.
3. Slidetheincludedspringwashers(B)overthescrewposts(A)andattachthescrew
poststothebackoftheradio.
4. Placetheradioinfrontofthedashboardopeningsothewiringcanbebroughtthrough
theopening.
5. Aftercompletingthewiringconnections,turntheradioontoconfirmoperation(vehicle
accessoryswitchmustbeon).Iftheradiodoesnotoperate,recheckallwiringuntilthe
problemiscorrected.Onceproperoperationisachieved,turntheaccessoryswitchoff
andproceedwithfinalmountingoftheradio.Refertothe“WiringDiagram”onpage5.
NOTE:Beforefinalinstallation,testthewiringconnectionstomakesuretheunitiscon-
nectedproperlyandthesystemworks.
6. Inserttheradiointothemountinghole.
7. Placethe“U”bracket(C)overthescrewpostsandsecuretheradiotothedashusing
theincludedhexnuts(D).Ifnecessary,cutthescoremarks(E)oneithersideofthe
