The radio gets its power from the "ACC" fuse and the "DOME" fuse. Each one is on a different fuse box. If the dome light works its not that fuse. If the shift lock and cigarette lighter work its not the ACC fuse.
Base line radio,... Orange -hot all the time, Acc fuse ..-20amp. Yellow ,Hot -key on.. Radio fuse -10amp.... Delco, Bose system...Orange,-20amp ARC fuse..Hot all the time, Yellow, radio fuse, -10 amp, hot with key on. Your second orange wire powers your Amp Relay, in the Acc fuse,- 20 amp ..it has a constant hot, or power..so you might be getting power @ the Radio, but Nothing out the speakers.. Hope that helps..
Check to make sure all fuse associate to the radio/navigation is good, sometime like the acc socket fuse being blown could cause the thing to not work also, so make sure you get to all the fuse to make sure they are not blown. After that, there maybe a fuse located with the navigation unit behind the radio/navigation unit that may be blown. If there isn't or is still good, check all connection to it. If all is good then your unit could be history and you may need to take it to a dealship to actaully see what is going on.
it is usually the accessories fuse under the bonnet or under the dash ,but the radio may also have its own line fuse in the power wire that goes into the radio,you may have to pull the radio out to get at it....hope this helps....cheers
I have looked and looked for this myself. I belive since one of the wires runs to the ecu. for the acc power it is branched off of some other . If you need a good reliable place to pull power. Use the power windows Breaker / fuse its on the passanger side it is on acc power for the key.
The other Direct battery feed for the radio is protected in the left fuse box on the drivers side.
Check all fuses for radio...In addition to the fuse in the fuse box, there could be inline fuses tucked up under dash or in rear of radio. There should be 2 live positive wires going to radio...one constant power, the other live when key is On or Acc..also check for good earth connection. Hope this helps.
You should have 2 positive power supplies to your radio...one always on, the other only on when ignition is in ON or ACC position. Hope this helps. There are sometimes inline fuses tucked up under dash.
Please check your owners manual for the location of the 10 amp fuse for the radio. On some models you have to reset the security feature on the radio/CD player for it to work.
The info below has been stated to work on a no go radio. I have not confirmed this procedure.
Remove the lower fuse box cover, with the power off, removed the 10 Amp fuse for the "Radio." the fuse may be good. Fuses are diagrammed in the owner's manual. With the fuse removed, start the car, turn the car off, replace the fuse and turn the key to "ACC" to see if the radio was "Reset."
Would the alarm cause the radio to malfunction? If your Anti Theft lock was activated check your owners manual under radio and check for a 4 number password. Sometimes it is taped to the upper part of the glove box. If you do not have the CODE you will need to take the vehicle to a dealership or a repair center. They use your vehicles vin number get the code.
Other than the dome light, all of the other electrical you
posted operate using the ACC terminal of the IGN switch. The most
likely then would be a loose connector either of the wiring harness,
relay base or fuse holder fed by the ACC B+. Determining which is a
matter of tracing the wiring from the ACC terminal to the fuse
box/feeder (in some instances, there would be a relays likewise). From
the fuse box/feeder it would go to the different fuses for the radio,
defogger, auto door lock. The fuse(s) may be OK but their connectors
might be loose and/or the main connector that feeds the fuse box/feeder
being the common denominator.
The dome light should work even
with no key in IGN swtich turned to ACC. But then again, it is fed from
the fuse box/block straight from the battery's + terminal. Which leads
back to the connector to the fuse box/block. Your best bet would be to
remove/reconnect the different connectors going to and from the said
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
