Astra Radio Problem - Bryden
I\'ve recently had my coded radio cassette player stolen from my Vauxhall Astra (don\'t know why - idiots), and have just got a replacement from a friend - not a like for like but a standard unit. Plugged in fine etc. but the player appears to be blocked i.e. no sound.

Is some sort of management system blocking my radio thinking it is still the old one and if so is there anyway around this? I obviously don\'t have the old unit to type a number back in.

Thanks for any help.

Is the replacement from another Vauxhall, and is the separate dash display illuminating?
From previous threads here, you'll need to get the the stereo "married" up to the display by your local Vaux dealer.

No, the replacement is a non Vaux generic Blaupunkt, and the dash does illuminate when connected. From John's reply I'm thinking there is a wiring mismatch. I may have to admit defeat and go to my Vaux dealer.

From what you say, this new radio won't drive the remote display. However, what you'll find I believe, even when the wiring is corrected, is that when the radio is switched on the remote display will blank, as it's looking for an input from the radio. That's why I changed back to a VX radio in my my car - I found the blank display very irritating.

A local radio specialist may also be able to help with the wiring.

I assume you've entered the radio code for the radio you now have? That code will be specific to the radio, not your car, and your old number won't work. I found that, when fitting a replacement Vx radio, the display worked fine for the 'decoding' sequence of the radio, even though the display wasn't correctly set for my car, and didn't subsequently show any tuning data. However, if it's an original Vauxhall radio the excellent 'tweak' given here before which toggles the radio display on 'original' Vauxhall radios, may solve the display problem highlighted by DD. That said, The lack of display doesn't mute the radio, all the buttons work, and it's easy to find a station to tune to - even if you've no indication what it is! What should happen, if the radio's not properly set for the display in the car, is that the date display blanks when the radio is swithed on. This confirms it's trying to drive the display.

With the Ignition on
Press and hold the 4 & 6 buttons on the set
Then switch on the radio keeping the 4 & 6 pressed
and the display will show "10-digit" which will then "toggles" to "8-digit"

(Thanks to the contributor, whose name I've forgotten!)

If it's not a Vx radio, then it's possible the connector at the rear is wrongly laid out - I'm sure it's been commented that Vx use a non standard connector layout.

If it's just no sound, make sure the thieves have not damaged the speaker connections or pulled the wires out of another connection further along. Another possibility is that the replacement unit is faulty.

Have you tried fitting a Radio Wiring harness? Available from Halfords for most cars - converts the OEM wiring pattern to standard audio pattern. Only a few pounds - so probably worth trying if there is one available for your car.

Most of those wiring harnesses will tell you there is a slightly different wiring combination for Vauxhall and VW cars.
