    Stereo wiring- easy or not?

    Hello all, i'm new to this site but i imagine i'll be reading it alot now i've found it!

    I've got a 1.6 mk4 astra, without the steering wheel volume controls. I'm looking to buy a new stereo but i'm loath to paying halfords nigh on £40 to install it. Anyone know how complicated it would be to wire 1 in myself? I'm not a technical person, but i know 1 end of a screw driver from the other and could follow a simple-ish diagram. However, if there's millions of wires behing there i'd rather leave it to a pro!

    Also, if i was to replace the vauxhall fitted stereo, would the new one still link the display in the centre of the dashboard?

    Any help would be appreciated, cheers.

    If it's a brand new headunit with ISO connectors on it then it couldn't be made much easier to fit mate

    First you need to remove the 4 small grub screws with allen key heads from the holes in the front of the headunit you you can get the removal tools in. Removal tools can be got from halfords for a few £ and are U shapped bits of metal. Once you see them you may be able to make your own to save a few ££

    Once the headunits out you need to remove the cage thats held in with a single Torx 20 screw at the middle back of the cage.

    Once thats out your left with the connectors to plug your new wiring into and all you need to do is swap the red and yellow wires over on your new wiring so it keeps it's memory. A aerial adaptor is also needed but if your radio is brand new that should come in the box

    Make sure you secure the new cage in firmly. Plug everything in and test it fully taking keys out the ignition to see if it saves the memory of the radio and once your happy its alright slot it into place

    Look, in all honesty mate (and this is coming from a Halfords employee here!) it is a piece of the proverbial wee wee to fit. It's actually one of the easiest cars to fit to, even including the steering wheel remote. Just a case of plugging in iso blocks!

    There is a vid of how to remove the old one, and the new one is easy enough!

    What neck of the woods are you from?

    Cheers fellas,

    When you say swap the red and yellow wires over to keep memory, will that be obvious when i look at it?

    I'm from birmingham by the way, and thanks for your honesty halfords man!!

    Where are you located, maybe a member can help you with the install if you are unsure what to do.

    Possibly stick a thread on your regional section for help

    Oh yeah

    When you open the box 80% of headunits come with a small wiring loom with a red and yellow wire, quick swap around and job done

    Once you have it in front of you it will all make sense
