Your fuses one of them of 3 is bad depending on who owned vehicle before you they might have used more than 2 fuses at a time

you have fuse box
then you have wired fuse on radio

Astra coded radio cant enter code??

I would suggest that your radio got a voltage surge when your battery was recently removed and re-connected. I would either:

1) Remove radio (if you have the special tool), unplug and re-connect harness, or

2) Pull the fuse in the fuse box for the radio (may be two), or

3) Disconnect the negative post to the battery, wait 30 seconds and re-apply (very quickly).

If the display does not reappear, I'm afraid the radio is damaged. Let me know.

When you disconnect your battery and then reconnect itagain, it disables the radio. This is an anti-theft protection for your carradio.
The enable your radio the activation code is in your vehicle owner's manual. Ifyou do not have this code you need to go to your vehicle manufacturer's servicecentre and get them to enter this code for you.

How do I get a signal back after I have a dead battery? The XM screen says "not ready". Xm said I have to go back to the auto dealer to get a signal back. This doesn't seem right.

With all the anti-theft deterrents placed in cars now if you disconnect the battery so as to bypass the alarm (even though all your doing is replacing the battery) in allot of cases the factory radio disables itself to render it useless to someone stealing it. The reset code should have come in your owners manual and if you don't have it then you will have to go to the dealer and prove ownership. They should provide you with the needed code but then may charge you to reset it. In the future if you replace the battery and the previous one isn't completely dead a set of small jumper wires to keep 12vdc on your electrical system will prevent this in the future.

Poineer III D wont turn on

If the negative ground was not disconnected, you may have popped a fuse on the radio, if it has one. Check the back of the radio and the fuses there. Always remember to disconnect the ground when working with the electrical system.

JVC KS F90 Radio cassette loses all settings when switched off

Your radio probably needs a constant live to retain the radio settings. It may be that your radio has 2 live wires. 1 live that operates the radio coming from the ignition and 1 coming from a constant live that just gives enough power to retain the memory settings.

If you are going long periods of not using the MGB I would disconnect the battery to stop the it draining. If your battery goes completely flat it will damage the battery

My radio's dead

Sorry it took so long to get back on this. I just moved from Detroit to San Antonio and am still getting sorted out.

You can use any long slim metal to get the radio out. Something like a couple of butter knives are about the right size. You push one in on each side of the radio between the radio and the sleeve that holds the radio. Push them in as far as they will go near the middle part of the radio. Once they are all the way in they should release the catches that hold the radio in place, then just pull the radio out. The radio may also have a fuse right at the connector for the plug. It will be a plastic blade fuse normally a red one (10 amps) so check that as well. It plugs right into the radio and is part of the jack that the harness plugs into.

Let me know if you need any more help.

Car radio Code

You will probably have to contact the manufacturer and speak to a technician to get the factory reset code. Chances are, the code was put in by the previous owner of the car. When this code is entered, it makes it impossible for the unit to operate if stolen. Hope this helps...

DEH-1900MP - lost functionallity after disconect/connect batery

Yes for some radio's if you take away power it has a theft lock and will not let you back in except if you have the code. To reset you must take power away from it. I would suggest if you don't want to take cd player out of car then disconnect battery. then when reconnect eject. May have to set for a moment.

The radio plays the CD but the faceplate is dead

Maybe the radio need to be reset. Try disconnecting the battery cable for 5 to ten minutes. If that does not work, the radio will need to be serviced or replaced. Good Luck
