Change the fuse, if it still doesn't work then the circuit can be tested before spending the money on a new radio

Unfortunately, this kind of connection can actually kill the radio. If the fuse for the entertainment system didn't blow, or blows as soon as you replace it and turn it on, then, es tut mir leid, das radio ist kaput.

SOURCE: Hi, problem with 2007 VW Citi Golf radio security code.

The radio is in Lock-Out mode. You only get two attempts to enter the code, then it enters Lock-Out mode.
Put the key in ignition and turn on the radio for an hour (maybe a bit more). The radio should reset itself after about an hour and then you can re enter the code.

Have you checked the radio fuse? You may have blown the fuse when you jumped the car. The fuse box should be out under the hood encased in black plastic.

How can I jumpstart my car from my friends 2009Audi A8


You want to use the battery in the engine compartment, the one the alternator charges. I just connect the batteries directly pole to pole. When you rev up the engine the alternator will increase the output going into your battery.

2001 Mazda protege radio and lights in car not working after jumper cable s were hooked up backwards


Connecting jumper cables the wrong wat around most likely has damaged electronic components such as a radio and computer.
Check the fuse box and replace any blown fuses.
If you still have problems then get an auto electrician to fix your car.

I'm trying to install a new battery in my 1984 Nissan Sentra. When I hook up the terminals, the wiring starts to smoke leading me to believe that the hook up is backwards. What is the correct hook up for...


Hi and welcome to FixYa, I am Kelly (Electrician since late 1960's)

Ground goes to the - pole. Hooking it up backwards can damage your alternator, wiring harnesses and fuse links. (Fuse link damage is a nightmare to sort out!) What you do by hooking up a battery backwards is turn your vehicle wiring harness into a giant heating element. (<-Very bad!) If you just changed the battery and then you hooked up the cables with the smoking cable result you certainly did connect the cables backwards. The ground cable... will connect to chassis and in most cases the engine body / transmission somewhere.
The positive cable will eventually connect to the starter. Follow the ground lead from the battery to the chassis or engine body connection. (metal to metal contact) Once your sure that is the ground cable; connect it to the - post of the battery AFTER connecting the positive post terminal.
If you have a newer audio system you will have lost your radio codes. We can not provide the codes for anti-theft reasons. Activation Codes must be from the car dealer or audio system retailer.
Thanks for choosing FixYa,
Kelly

Run the car, then disconnect the negative pole on the battery, then the positive pole.

If the car keeps running then your new alternator is working properly.

If your car stops then your new alternator is bad.

The car was connected to jumper cables the wrong way


The problem is likely the fuse on the back of the stock radio. The VAG tool communicates through the radio, believe it or not. Your radio should also be dead after the reversed battery jump. If this is the case, pull it out of the dash and there's a 7.5 amp brown fuse alongside the cable harness on the back corner. Replace this and see if the problem is fixed.
