Easiest thing to check is all the fuses, you could have blown one when you was fitting it, if they are all fine, check your wires are the right way around, check you lives for voltage when the ignition is on and of.

its weird beacuse when i bought the mk3 sqaureback, it came with tape/radio and that was all working. But as soon as i replaced the tape/radio with the headunit, its not working.

i will check the fuses tho thanks mate :-)

hopefully that is whats wrong with it cos i bought the headunit brand new so theres nothing wrong with that.

i wouldnt always go by brand new = must be working i work in halfords fitting head units and you will be surprised how many dont work when u get them outa the box and surprisingly not always ripspeed

oh :cry:

i hope it is only the fuse tho :(

its my first car, i dont want things to go wrong already lol

everything connected up properly and stuff

tis hard to get the iso wiring the wrong way round I'm sure its fine probily fuse can happen quite easily... cant say I've fitted in a mk3 polo but I'm guessing its the same wiring as the mk2 or mk3 gold and is usualy connect hte blocks and away you go... except in mk 3 wer you switch iggnition and power over

hmm just had my uncle fix my headunit problem for me haha :p it was somit to do with these 'bullet connectors' on the new connectors that came with the radio. An something about that i have a constant igniton power supply so i can turn the radio on wheter the key is in or not ?

anyhow mines working.. just those standards speakers are rubbish!!!

one way of checking if the fuse is blown is see if the lighter works.. or the cieling light.

i followed the instructions for it as i had no idea how to fit it lol

and they show u a diagram specifically for volkswagens!

so everything is how it should be :?

the ceiling light works so its not the fuse

cld it be the bullet connectors????

how did u get it fixed?

basically the red and yellow wires need to be going into one slot... different on each heat unit... normally has bullet conectors so you can do this... gues this is wired like a mk2 golf

well mine had 3 wires with bullet connectors but only 2 of them can be connected(1 yellow 2 red). In my manual it says to change these around and it should work. at first i got the power working(red light was flashing on the unit) then there was something to do with the memory. You should get someone to help you hold the radio while you change the wires round so you can see wheter its working or not.

Oh an check the fuse in the back of the stereo.

Cant say much more as thats all i had to do :)

mine said u should change the connectors aswell, so i did that and fitted the headunit in.

I've got the red flashing light, but it jsut wont turn on :cry:

Weird even if the lives are around the wrong way it will still turn on but it would just forget your radio stations every time you switched it of. Have you checked the fuses yet?

I believe from memory it is the 3rd or 4th fuse across the top in the fuse box (which is located behind the drivers side glove box) you should also check the fuse in the headunit.

The fuses should be labeled on the rear of the drivers glovebox to tell you which one is which.

I would advise you check them all though as something else might have blown before you got the car, this could solve a few problems that you didnt know about. But just remember which hole you took which fuse out, so only do it one at a time.

i cant get the radio stations because i couldnt plug the aerial thing in :?

the same fuse powers the radio,lighter socket and interior light, and they all work......

also, I'm having problems taking the cd player back out of the dashboard :angry:

Use the radiokeys that came with you stereo to unlock it from the frame.

you shouldnt put the unit in fully until you know its working.

Do a voltage check on the ISO power supply leads... If you dont understand that then ignore it an try somit else...

Have you got a spare radio or perhaps the one that came with the car?

You need a voltage meter. you check the red wires i think.. an hold one on a ground. but forget that its not likley to be the problem.

Did your original radio work? If so then you are just gunna have to keep trying different combinations on the bullet connectors... not much else you can do but take it back to the shop if you cant get it working.
