What kind of screwdriver do you need to take the radio out? I just tried to fit my new head unit and it has these funky 6 notch screwheads and none of the phillips or flatblades work :p Do they sell them in B&Q?

Also, how on earth do you take the negative lead off the battery. Its really tight on and i can't undo it with pliers. Will i get a shock off it? Do i need to remove the negative lead if I'm changing the stereo?

"6-notch" would be Torx, I believe...

On the other hand, specific radio removal tools can be bought from Halfords or a local motor factors/car audio shop. They're not cheap tough!

Most thngs in these use Torx screws.You can buy a set in B & Q.

The Negative lead is bolted so using pliers is not really good.

Hmm ok, and I guess i WILL need to disconnect the negative lead when changing the stereo right? Will i get a shock?

No you won,t get a shock.Its if you arc the positive lead to earth that you will get a shock.

You should be ok to change the HU without disconnecting the battery (unless you need to access the rear of the fusebox). The octy2 HU is secured using standard Torx screws. Most toolkits should have appropriate bits.

Thanks all..

Leave well alone, sounds as if though you are going to make a right botch. Pliers to undo a bolt to remove the earth wire clamp, trying to undo torx bolts with philips and flat screwdrivers is making me wince.

You need a Torx, I can't remember if it was T15 or T25, but the 10-15-20-25-30 set is rather cheap. You can leave the battery in, I did it myself.

The radio, when put back after a couple hours retained it's memorized stations and everything.

If you need extra safety take the fuse out. However, you sound not to know too well what you are doing, so I'd take it to a pro, or at least somebody with better knowledge in the electricity department.

Did you sort it out?

10mm spanner or socket is what you want for the battery but as above not really necessary if you are just swapping over, if you are messing with the wires then yes take it off.

erm, yeah, I'm with Jamesmckelvie on that one! I applaud the fact that you want to have a crack yourself, but if you're trying to bodge it without knowing what tools you need, and not knowing what they're called either, you're probably better off getting someone who DOES know what they're doing to do it. Not being snobby, just trying to save your car from possible irreversible damage (i'm mainly thinking cosmetic) on the offchance you balls it up from lack of knowledge, if you get my drift. It's not fun getting a pro to fix what you've ballsed up: I know from when I tried redoing the timing belt on my first golf. No damage done, but I realised something wasn't right when it sounded like a 70's Dodge Charger! Still haven't got my head round doing the timing so I never touch it nowadays!

If you are insistant on trying to do this, I'd like to recommend Halfords 120 piece socket set as it has almost everything you'll ever need, without wanting to sound condescending, for what appears to be you're possible level of maintenance and a whole load of other stuff for round the home to boot. At the mo, it's currently on sale one third off at £99. Got one myself, and it's never let me down. It also has a lifetime warranty so you'll never need to buy another! Hate to give Halfrauds free big-up, but their professional range socket sets are the best thing they do by a long shot! Brilliant!
