Blaupunkt 420 Stereo removal problems

Hi,

I have a 2000 model Holden/Opel Astra City Hatch. It came standard with radio cassette Blaupunkt 420 head unit in it. Im trying to remove this so as I can put a new CD head unit.

The problem is I can't get the old blaupunkt stereo out. Does anyone know how these units come out or know where i can find installation manuals for them or anything?

The unit comes with 4 small allen key bolts in the front of the unit. I've tried taking them out and using some coat hanger wire to poke down there to see if i could pop the unit out somehow but that wont work. It feels like there is still something holding the unit in and i can't get it out.

I've also had trouble getting any of the plastic dash around the unit off so as i can take a closer look at things.

CAN ANYONE HELP ME? Please any comments/help would be great.

I pulled the Blaupunkt radio out of a 2004 Pontiac GTO yesterday (basically a Holden) that had the four holes like you described. I used 4 straight "pick" tools and pushed them towards the outside of the radio like a Ford, and pulled the radio out. It did take two sets of hands though to get it out.

What is a "pick" tool?

I tried using 4 striaght bits of coat hanger wire.... is that the same sort of thing?

Sorry if the question seems a bit stupid, I'm new to the car audio get up.

Problem solved

well, for the record this is how you get the head unit out.

The Blaupunkt 420 needs a set of special made "keys" that you slot through the four small holes. These keys depress 4 hooks the prevent the unit form sliding out. I do believe you could use coat hanger wire, you just need to know where to push them out at the right spot.

Thanks for your help crx4luke.

its a small hand tool about the size of a mini screwdriver, but the one i used just comes to a point. They come in 90 degree angles, and a hook style as well. very useful little tools when it comes to working on cars.

The OP in this thread hasn't been here for 8 years (and the person answering him hasn't visited for 3), so I don't anticipate either member will be jumping in.

This forum is primarily North American, and we didn't get the Astra here until the late 2000's as a Saturn (then imported through GM)...unfortunately this was a different vehicle with different radio wiring. A UK-based Vauxhall or Opel specific forum may be a better bet, but try this (searched up via "the Google") and see if the colours sound right:
