My car stereo sometimes play and sometimes not. I think it is because of virus. Please help.

Sounds like you have a dodgy connection in stereo's wiring if it works sometimes. Hope this helps.

i know it sounds like its too easy to be true, but try checknig all the fuses. sometimes cd players have fuses inside them also. i dont reccomend taking it apart, but if your desperate try it

Not every car stereo can play every song in a usb.

This deppends on how many songs and how many folders you have in your USB, regardless of the USB's capacity. My car stereo for example, can only play about 50 songs pero folder and i think it tops at 9 folders.

Try to organize your music in folders and change the names of the songs taking every "·$&%/&$/)(=)(( Symbol and non regular character out.

Or better, get your car's manual and it might say how many songs it can play. i think mine cant read over 1.5gb. if it doesnt say, you just have to try and work with it till you get it figured out.

The last thing i try and it might work:
Cut everything out of your USB, format it and then paste everything back this refreshes the USB and sometimes it works.

Sorry about my english.

it sounds that your lens could be damage or your loading mechanism, 1st try using a cleaner to clean the lens if that does not work , your either need to get the factory stereo service or start thinking of a new radio

had the same problem. volume super high or nothing.auto wreckers $100.00 problem fixed

Its my belief that stereos in vehicles can become corrupted by maleware code. Do you play mp3, ipod, or burned cds in the stereo. I broke my factory stereo when I played a burned cd once. The market is ripe for virus and maleware protection for your car stereo so don't be surprised if you see virus protection and their virus creating friends on the scene soon. "Try reseting the stereo". You can also try to pull the ground to the car battery for 2 minutes but you will have to let the car idle for 10 minutes after you reconnect the post to set the idle correctly and let the car essentially reboot. Also jump starting a vehicle could cause malfunctions in the stereo if not breaking the electronics inside, very likely in the colder climates.

? u need antivirus for your phone you cant get antivirus for your phone

There is a small hole at the bottom of the stereo face that will reset the system. I pushed a pen tip into the hole and it turned the stereo off. When I removed the pen, the system turned on and the CD ejected. Problem solved.

I didnt think alpines had codes?

are you sure it has one?

sounds more like a connection problem

you need a ford to pioneer wiring adapter. available at any stereo shop.
