Re: RADIO NOT WORKING AND I DON'T KNOW NUMBER FUSE TO...
Some stereos have a fuse on the back of them usually a 15 amp. Some have an inline fuse round inside a small holder on the power in wire, they are red or clear. If you are refering to as which fuse to change in yours cars fuse box it is usually the one that goes to the Accesories, the lid to the fuse box usually has this information, or your owners manual, or you can pick up a motor manual for you cars make, model, and year at your local auto supply store.

Absolutely. The ground wire for a separate amp will need to have a chassis ground, or it will attempt to draw a ground through the radio. Unfortunately, the amp draws allot of current, and the ground foils(all the copper traces in your radio) cannot support an amp ground. Most likely, those traces are probably burnt open. Additionally, these new radios have fuses inline with the foil. They do not look like fuses, so I wouldn't recommend trying to replace them. Additionally, if you pull the cover off, you could potentially destroy many components(mostly ICs) due to lack of ESD precautions(Electrostatic Discharge). If you require more assistance, or would like to inquire about having you Pioneer repaired, please visit my website at audioserviceclinic.com. BTW, I worked at Pioneer, as the Field Service Engineer for all audio products. Thank you.
Just had the same thing happen to my new pioneer system. My truck battery died because I was jamming to the new installation, and the system just suddenly turned off. I charged the battery and the unit came on all the lights menus and displays worked like normal but there was no sound coming from the speakers. I checked all the fuses in the truck but none were burnt out. So I remembered there was a fuse on the back if the unit so I had to pull the unit back out. I checked the fuse and it was fine. I unplugged the wiring harness from the unit, plugged it back in and IT WORKED so I'm not sure exactly what was wrong with it, but I suspect when I unplugged the harness it reset the unit. So maybe this will work for your installation as well. Not exactly a high tech answer but maybe it will help ya! Good luck
Depending on the radio, if you didnt touch your radio when you installed GPS then the CD player could be bad, check the manufactures website for troubleshooting tips then check google, also next time post the brand and model number so we can know what you have to help, hope this helps you.
buy a digital volt meter and start checking fuses for the radio at fuse panel . if blow replace it . if not blown remove radio from dash check to see if radio is still grounded . if still grounded take the volt meter turn on to dc volts and take black test lead touch to your radios ground the touch the red test lead to the red with to see if you get 12 volt with car on if not need to find out why .. take to professsinal ..
you can also check the yellow wire on radio it should have 12 volts allways doesnt matter if car in off or running this saves memory for clock and station presets.
if every thing is test out right then you need to buy new radio ..
if you dont feel good about doing this yourself find a mecp car audio installer and have them troubleshoot your problem maybe expensive but a good tech could find out problem with in the first 30 to 45 minutes it get 35.00 per hour to troubleshoot car audio system ...
It sounds like you had a power spike when you installed the new battery. I would check the 2 factory fuses for the radio, one will be for the radio ignition lead and one will be just battery lead (usally assosiated with the clock). Lastly if those 2 fuses were ok you may have to pull the deck and check the fuse in the back of the deck.
If the fuses are all ok and no wires are disconnected, then its possible that something else went out. Good luck and take care!
The most likely reason for this is normally the output amplifier IC in the radio. If this is the problem, you would need to have the IC replaced. One bad speaker can also cause all the speakers to stop working.
If you have a multimeter to check the voltages on the speaker wires I could giude you thru troubleshooting it. It is very common for the amplifier IC to go bad in these radios. I work at an authorized Pioneer repair center and have fixed countless numbers of these radios. But before anybody can be certain of the cause of your problem, some thngs must be checked using a multimeter. Let me know if you have one, I will then tell you how to check what needs to be checked.
A repair for this type of problem on this radio will normally be too expensive to make it worth fixing. These radios normally cost about $100 brand new in the U.S. and a repair for this problem at a service center would be very close to that same amount, making it a better idea to buy a new one. If you do the repair yourself, it would only cost about $30 for the part. But you would need to know how to solder very good and be able to remove the bad IC and solder the new one into the radio. If you are not able to do this very well, please consider replacing the radio with a new one. You would first need to determain if the radio is at fault by checking the voltages on the speaker wires. They should all be around 6.5 to 7.0 volts. That is the normal voltage for speaker wires for these type of radios.
My guess is that when you pushed the player into the dash, you pinched a power wire, resulting in a blown fuse. Check the vehicle's fuse box.
Most vehicles have at least two fuses that provide power to the radio, though they may not all be labeled as radio fuses. You may need to check all the fuses in the vehicle, including any fuse box under the hood.
