I can't find the original post, but I've got this saved as I'm going to give it a go next weekend.
"Basically when you take out the headunit there is already a plug going into the head unit for the blue and me, therefore you need to make an AUX cable and splice the wires in along with the existing Blue & Me Cable.
Once we had connected the Blue and Me cables and our newly made AUX Cable and switched to 'Media Player' it recognised both inputs so started playing songs I had on my memory stick and songs I had on my phone and the same time! lol!
I thought the solution would be to just plug out the blue and me and therefore, I could plug my AUX Lead in and switch to media player and it would play it.. Sure, I would loose Blue & Me but surely it would work? But it doesn't work like this, when you switch to Blue and Me it finds the AUX input and you can hear the song playing for 3 seconds before it says 'No Media Found' and switches back to FM Radio.
Solution? Well, we looked through the various options and none would allow the car to remain in 'Media Player' mode for any more than 3 seconds! I then came up with the idea of creating a short 10 second Silent MP3 file and looping it.. So the 'Media Player' option would stay enabled as before. It would therefore still play both my memory stick song and Aux input at the same time, but if the only thing on the memory stick was this silent file then all you can hear is whatever you connect to your Aux Cable
Problem solved. Credit goes to Dad for 99% of it, Silent MP3 idea I'm taking the credit for! lol!
I realise that is hard to follow but if anyone wants I can make a guide in more clear terms.
The main jist of this is basically Blue and ME has no option for AUX but you can trick it into using the exisiting 'Media Player' option as a way of playing your AUX input."
It doesn't look to hard to do.
