Thanks mate, I’ll give that a tryThat radio is fine. You just need to make sure it is connected to the aerial with the coax on the back (and the integrity of the coax and plug). You do not need to have the little tools to extract it. If you can reach behind the plastics, at the back you will find the whole thing is held in place with one big nut on a 6mm stud poking out of the back of the console. Undo the nut and the whole thing (radio and surround) will slide out.
I would also suggest you check your speakers. When I checked the ones in the spares car I bought (92 Si, wrecked by a front impact) they were all shagged so couldn't use any of them in my GTI. I am telling you this because they were shagged by age not fiddling with the system. They were all intact (as in nobody had been in there) but the paper cones were all disintegrated around the outer edge. The Si was very well maintained as opposed to my GTi.
If you do however find the radio is shagged, I have an identical one or two spares (one out of my own Si, one out of the GTi).
That said, I would suggest if you want to change the radio, go for an OEM Honda out of early 2000 cars (doesn't matter which, they're all the same as long as they are single DIN). I would go for a full logic control but that's just me. Those are well made high quality radios. If you can get the speakers with the head unit, even better. You can get a unit with cassette or with CD, whatever blows your budget (expect to pay zip to 20 bucks). Don't be daft and go for aftermarket. Aftermarket will never beat OEM quality of a serious manufacturer who employs specialist engineers to spend time and money to make sure they get it right. Some had codes some didn't (it was up to the buyer to request the code be eliminated when purchasing the car new). Make sure you get the code if it has one and test it. Honda can sometimes help if you have the radio numbers or the car's VIN.
