Hi line and lapower mp3 bluetooth

[Milo]

Hi mates

I just bought this 'lapower' Chinese mp3 and bluetooth box:
http://www.ebay.co.uk/itm/Car-Blueto...-/111727574790
and thought it will fit straight away in place of my cd changer. But after removing the changer and head unit I realized that I had different connectors. Back of the head unit looks like that:





and the connectors from the mp3 box is this one:




but in some thread here someone said that there should be bmw connector somewhere underneath aircon panel? Is there any chance to connect this mp3 unit right there? Just asking if it's worth to remove aircon panel and check it out or should I just send the unit back to the seller?

You may be able to connect it to the lead that went to your cd changer. The bad news is that you'll probably have to bypass the plugs on both leads and use crimps or a chocblock type connector. Before you do you'll need to know the wiring of the chinese unit lead. The CD changer lead from the hi-line system has two wires each for left and right audio (although there's no problem tying the earths together) power +ve and earth (again you can tie the earth with the audio earths) and lastly the IBUS wire. It may be that the chinese unit may not work with the highline if it doesn't communicate via IBUS - I don't know. I seem to recall the cd changer for the highline being different to the ones for the other stereo systems - althougth the one in our 1.8 with the non-highline system does look the same as a highline one (I haven't had it out of the glovebox to check though). Plugging the chinese cd changer into the back of the (highline) head unit is a non-starter, it's actually the radio/amplifier unit in the boot that it connects to (the controller of the highline system).

Trust me not to read the whole post properly. the lead(s) pictured above may be the correct solution. The large square 17 pin plug to socket bit should plug into the socket behind the ashtray, the plug that currently plugs into that socket then plugs into the socket part of the new lead and the white plug from the new chinese unit plugs into the white plug from it.

to get at it all you'll have to remove the head (already done ), remove the aircon panel, remove the switch panel and any switches above the ashtray and then remove the ashtray (it's all one unit with the cupholder(s) and lighter socket). You should then be able to see the large square 17 pin plug behind where the ashtray was to the left wedged down at the bottom.

Give that a go and let us know how you get on.

P.S
I see you are only down in Bedworth - if you get stuck we can always organize you to pop up here (Northampton) and get some help.

Ok, here's the update. I removed the ashtray unit and found the proper plug. However there's still one small plug which I cannot connect to anything. There's 8 wires from the mp3 device, 4 wires are connected to that bmw plug and 4 are going to this smaller plug...







After disconnecting cd changer (due to box manual) the device is visible on the system. I can switch folders on usb, I can pair it with my mobile or use aux in cable. But there's no sound at all. Any suggestions?



EDIT:
there's the diagram of that plug from bmw






but unfortunately I cannot see which wires are connected in the plug. On the other side I can see those wires:

It may need connecting to the CD changer lead if the Bluetooth unit is designed to be fitted in place of the CD changer. It would then use the existing audio output circuit used by the CD changer.

[Milo]

It's the solution probably. I just cannot find the diagram of the cd changer plug. Does anyone of you have it?

[raykay]

See if the black connector fits the connector on the cable to the CD changer (the CD changer end).

I believe the black 10 pin plug will be a match for the 10 pin plug shown in this drawing (Showing pin 1=Data...) - The wires going to 17pin part of the plug must just be for power and maybe phone mute input) I don't think the match for this plug is there in the front console (but can't be sure). You'll have to match it into the cd changer cable. Or maybe you could change your installation location and install it in the boot next to the radio and connect it directly to the radio module. I've no idea if the plug will fit straight in place of the one connected into the radio. You'll just have to pull the radio unit to find out. There's an archive thread here the post from t_i_m list's the pinouts for the rover cd changer plug.

Hopefully that'll help you going forward.

Once the earths are all connected properly you'll hopefully be rid of any buzzy noises. On my installation the CD L/R signal grounds and power earth are all tied together and seem OK even at ear-splitting volume with no buzz in the silent parts. Still happy to take a look and see if able to help. You could always pop over to our meetup of the Northants Sausage & Spanners group if you like See the site here Sign up and come and join in!

Thank you for the info. To be quite honest I was so busy that I had no time to work on it. At the moment I still have the device connected as mono with buzzing noise. But anyway I can play songs from my mobile, answer phone calls using steering wheel etc.
I will try to finish the job as soon as the weather will be nicer as I don't have the garage at the moment

Would not like any buzzing noises, think there were a few posts on why this is happening and what can be done.

Have a connect2 to play with now, no need (yet?) for bluetooth.
Will start on a symphony version first (should be designed for it) and see if it works and what it can do.
Only after that will have a go at the highline equiped 75, which came with a number of leads as it had a standard 1-din headunit and now is a normal fully working highline.
