Astra radio not coding - Ti mbo
I recently bought a used Vauxhall Astra and after some work involving disconnecting the battery, I needed to re code the radio. Using the code I got with the vehicle, I tried four times without success to re activate the radio. After some digging around, I found the set had been upgraded from a CAR 400 to a CDR 500. You guessed it I was using the wrong code. I managed to find the correct code but I have a problem.
When I switch the radio on it reads SAFE. I switch it off and back on holding AS button down at the same time. The screen reads 6 SAFE. I have successfully entered a code (although the wrong one) four times previously .

I understand there is a time out period to wait before another code can be entered. The problem is I have ran the car for periods of over 30 minutes at a time with the radio switched on but the 6 SAFE will not change to
6 - - - - as it should. I believe the waiting period should be at the most 20 minutes.

Can anybody help me out please. I should have 10 attempts before the set is useless.

Many thanks in advance

Nope.

The first two attempts is approx 10 seconds, After this, it increases to 10 minutes. With each further failed attempt after this the waiting time is doubled, reaching 640 minutes by the ninth attempt.

ie,

Attempt 1 - wait 10 secs.
Attempt 2 - wait 10 secs.
Attempt 3 - wait 10 mins.
Attempt 4 - wait 20 mins.
Attempt 5 - wait 40 mins.
Attempt 6 - wait 80 mins. (1 hr 20 mins)
Attempt 7 - wait 160 mins. (2 hrs 40 mins)
Attempt 8 - wait 320 mins. (5 hrs 20 mins)
Attempt 9 - wait 640 mins. (10 hrs 40 mins)
Attempt 10 - landfill.

As the display is showing 6 SAFE, you're gonna have to wait 1hr 20 mins before trying again. And by wait, that means leaving the set switched on and also the ignition key as well.

The waiting time gets longer following incorrect codes. Between the 3rd and 9th attempt the waiting time is 10 minutes, after the 9th attempt the waiting time goes up to 640 minutes.

Vauxhall state "It is therefore recommended to let an authorized Vauxhall dealer put the unit back into operation after the sixth unsuccessful attempt".

Many thanks for responding......another question, is it mechanically safe to leave the ignition and radio switched on for this lenghth of time ( 1hr 30 ish). I dont normally have a journey of this length.
Astra radio not coding - Ti mbo
I've just had a thought. On the first attempt, the screen shows 10 then 9 etc. If it's now showing 6 then surely I've had 4 attempts. The waiting time should not be as lengthy as quoted. Does actually driving the car with the radio on work or does it have to be stationary.
Astra radio not coding - Dynamic Dave
Timbo, yes my mistake. 6 attempts left, not as I suggested earlier. As long as both the ignition and stereo are left on, it doesn't matter if left stationary or driving it. Unlike the old days of burning out the HT coil if the igniton was left on, it won't harm your modern Astra if you do leave it switched on for the waiting period without the engine running. Some people however remove the stereo and connect it up to a separate power supply if it a very long waiting period.

As you've already had several attempts, it suggests that you have the wrong code.

You could try asking politely on radiocode.proboards6.com/index.cgi to see if the code that someone *may* give you is the same one that you're currently trying.
Astra radio not coding - Ti mbo
Dave.....many thanks for your reply. I believe I now have the correct code but I am unable to try it as all I get on the display is 6 SAFE. As I stated I have driven with this showing for about four days, with an average driving time of half hour at a time. At the end of my trip, without turning off the engine, I switch off the radio and back on holding down the AS button. Each time it just shows 6 SAFE. If I turn on the radio without pressing AS it just shows SAFE. Any more ideas as it appears to me it has locked up.

In the good old days of the Mk3 Cavalier you had to turn on ignition first with the key so all the dash warning lights were on (but engine not started) before you started coding procedure as follows:-

To Enter Code After Power Supply Broken:
With ignition key, switch on ignition so dash warnings light glow but don't start engine.
Switch on radio unit
Display shows SAFE after 3 seconds it shows 10 _ _ _ _
Enter four digit code you have using the station preset button 1,2,3 & 4. You keep pressing button 1 until the first code number reads correctly. then button 2 & so on.
Press AS button until it beeps confirmation & the radio starts.

If the wrong code has been entered the 10 _ _ _ _ becomes a 9 and so on until all 10 chances are used up.

This may still work in your case.

If I've read your message correctly, then you aren't accessing the coding procedure correctly. With the stereo off, you need to turn on the ignition, and then hold down the AS button and then turn on the stereo. No good doing this after your journey of 'x' minutes; you must do it right at the start and then wait for the timeout period to expire. If you do go for a drive whilst waiting, then start the engine before pressing the AS button - ect to go into the coding procedure, otherwise the power to the stereo will be cut off momentarily and you'll be back to square one again.

I take it you have the instructions for the stereo? If not, then I can post a link to a website that shows an extract from the instruction manual for the coding.

Victorbox, you appear to have one sentence missing from your instructions. Before switching on the radio unit, you need to press and hold down the AS button first.

"Victorbox, you appear to have one sentence missing from your instructions." Not from the Cavalier Grundig SC303 instructions I was quoting from, but possibly your extra (AS) line is needed for these new fangled VX units!

for these new fangled VX units!


New fangled ! On a mark3 astra I used to own you had to press and hold down the AS button before turning the radio on to enter the code after a poewr interuption.

Victorbox, you're quite correct. Although a lot of the stereo's do need to have the AS pressed beforehand.

many thanks for all your replies.........I know the procedure for entering the code. The problem is, I initially had the wrong code as the system had been upgraded. I now have the correct code but even after leaving it switched on for the dutation of my journeys, all I can get is 6 SAFE. When I switch it off and back on pressing AS it still just shows 6 SAFE. I cannot get it to show 6 ----.

I don't know anything about putting the code in these Vauxhall radios, but my understanding is if you put your key in the ignition and switch it to stage 1, the auxillary devices stage, then hold down AS and switch the radio on, then leave it for the desired time period without touching anything else, (this may be up to 1hr 20mins), the radio should then allow you to enter the correct code. The key is to leave the radio switched on for the correct duration, without interupting the power supply, ie don't switch it off until it allows you to enter the code.

T1mbo, if you're sure you're doing as the manual suggests and leaving it powered up until the timeout finishes, then you are going to have to let a Vaux dealer / audio specialist take a look at it for you. I have seen it mentioned on another forum where no matter how long it's left the 'x'SAFE (where 'x' is the number) doesn't disappear allowing another crack at putting in the code.

many thanks Dave..I was trying to avoid the possible cost of going to a dealer but it appears I have no option

Won't switching it off and back on restart the timer? I think you need to leave it on constantly with 6 SAFE showing for the 1hr. 20 mins., then it should chnage to 6 ----

I think I confused things earlier, but did post a followup explanation after T1mbo queried it. If the display is showing 6SAFE then there are 6 attempts remaining. Therefore the waiting period should be Attempt 5 - ie, wait 40 mins, not 1hr 20 mins.

To *hopefully* clear up the misunderstanding, I've added some additional text to my orignal time waiting periods.

Attempt 1 - wait 10 secs. (Display shows 10SAFE)
Attempt 2 - wait 10 secs. (Display shows 9SAFE)
Attempt 3 - wait 10 mins. (Display shows 8SAFE)
Attempt 4 - wait 20 mins. (Display shows 7SAFE)
Attempt 5 - wait 40 mins. (Display shows 6SAFE)
Attempt 6 - wait 80 mins. (1 hr 20 mins) (Display shows 5SAFE)
Attempt 7 - wait 160 mins. (2 hrs 40 mins) (Display shows 4SAFE)
Attempt 8 - wait 320 mins. (5 hrs 20 mins) (Display shows 3SAFE)
Attempt 9 - wait 640 mins. (10 hrs 40 mins) (Display shows 2SAFE)
Attempt 10 - landfill. (Display shows 1SAFE)

(I think)

Once again thanks for the prompt advice. I will give it one last go at leaving the radio and ignition on for at least 40 minutes and see if there is any change. i will let you know. Thanks

I'm not saying that Dynamic Dave is wrong, but I would leave the ignition/radio on for as long as it takes until it allows you to enter the code. I mean within reason, maybe a couple of hours or so, but if it hasn't sorted itself after 40 minutes then I would still leave a bit longer just in case. I would rather try this than have to sucumb to having a dealer/radio decoder do it for a fee.
Astra radio not coding - Ti mbo
Thanks simon, it was in my mind to perhaps leave it as long as I dare just to see what happened.
Astra radio not coding - Ti mbo
Roughly how long dare i leave it until it starts to flatten the battery. Thanks
Astra radio not coding - Simon
If you've got a decent battery and you only turn the ignition on to the first click (ie so that the dash lights DO NOT light up), you should be able to leave it for hours and hours and hours before a flat battery will be a problem. I would say that I would be tempted to leave it for up to four hours or so going on the information that we have about coding up this radio. I'm not saying that after four hours your battery will be going flat, but I think that it should have sorted itself out by then, but my patience would be running out by this point!
Astra radio not coding - Dynamic Dave
If you've got a decent battery and you only turn the ignition on to the first click (ie so that the dash
lights DO NOT light up),


I was always under the impression you needed to turn the key to position 2 (ie, so that the dash lights DO come on).

As I previously mentioned though, if it's a long waiting period, it's easier to remove the stereo and hook up to a 12volt power supply.
Astra radio not coding - Ti mbo
Many thanks for all your responses. For any future reference should anyone suffer the same fate; I turned the ignition to the first click, turned the radio on which showed 6 safe, went back after 1 hour and hey presto it had changed to 6 - - - -. After entering the code, pressing AS to accept I now have sound!!!!! Thanks again.
Astra radio not coding - Dynamic Dave
So it was just a case of playing the waiting game.

Congrats on finally getting it working again.

I must have been thinking of the older Vauxhalls where the stereo didn't come on with the igniton until the key was at position 2.

aaahh that was probably in the good old days when radios had 'real' on/off switches rather than just a push button controlled by software ;-)
