I put my input on the face of the head unit, looks stock but is a little awkward with a jack plugged in. I will put another input maybe above the cigi power plug.
Had another thought also but will require some more research, a Bluetooth input internally... We will see.

Quick instructions:

1. Remove your head unit & disconnect
2. Remove the top plate, 2 screws
3. Remove the cassette unit, 4 screws then lifts out
4. You will now see the circuit board clearly, look for an ic with the following numbers: (IC202) TEA6320
5. You will connect your ipod input to pins 11 & 22 via the small capacitor. pin 11 is left channel, pin 22 is right channel.
6. I will attach a photo showing my soldered connection & where to cut the track.
7. If you trace back from pin 11 & 22 you will see a small surface mount capacitor (a little brown rectangle), you can soldier to the top of this, your audio must go 'through' this to the IC. (if this makes sense)...
8. The track that goes from this soldered side to a small hole (this passes the circuit to the other side of the board) must be cut. I connected my jack plug to this too so it would still play 'am' if nothing was plugged in.
9. I used 'bread board' cables to connect to the board, they are thin & have a solid end (as in photo).

Quick I know, but I'm sure once head unit out you will see how easy (but fiddly) it is.
Please note that I accept no responsibility if something goes wrong. This does work & sounds great. The small tracks are delicate so take care, it is worth it, I no longer have any CDs in the changer–not required so might remove it.
Everything still works as it should with the addition of an ipod input.
You can of course use the input for anything:
Satnav audio, TV screen...

My AM button is now reffered to as 'Audio Mod'.

Diesel, this post was the reason I joined AULRO. I searched the US Rover boards and could not find this information anywhere. I actually live less than 140 miles from the place in the US that does this and just could not justify the price he charges. I knew the method to add an AUX input had to be simple and I can't thank you enough!

I was already thinking about a Bluetooth solution that required an AUX input and now that I have seen your solution, my mind has been racing on how to integrate a Belkin AirCast Auto HandsFree unit internally.

Thanks again for your generosity

Hello,

I followed the tutorial and finished the solder job. The stereo works fine (CD, FM, AM). When I plug my MP3 into the jack the AM cuts off and I can hear my audio in both left and right channels, but the audio volume is very very low. Could this be due to a bad ground? All solder connections and cuts look fine, the same goes for the solder on the 3.5mm jack. Any suggestions?

Amazing work guys !!! One question can I do this with my factory single cd player head unit which doesnt have a tape function what so ever?

I've wanted to do this for ages and finally bit the bullet yesterday. All went very well but I was a bit daunted by the tiny size of the solder points. I chickened out and took the earth to a nice big one on the other side of the chassis. I also managed to crack to front transparent plate when drilling it for the socket.......

I didn't bother with a switched socket as AM is useless here in the UK, but with growing use of digital (DA radio will be able to use a receiver with the mod.

Many many thanks and have made a suitable donation to a local charity.

I'm glad this mod is still being used, it is a daunting task when you first look at whats involved, but once started it really is easy.
I still occasionally receive thank you emails from folks who carried out this mod, just glad I could help.

I really must update the instructions, try to make them easier to follow...

When drilling the front of the unit, very slow & steady is the way.

Cheers,

Do you have volume control on the MP3 player? Try your earphone output and see if that works better, you should be able to change the output level with the volume control. The aux out put is normally at a fixed level which should be more than enough to drive the head unit.

Great post
