ccfj1 Posted June 4, 2008 Report Share Posted June 4, 2008 Hi All, I had a nokia bluetooth car kit (CK-1W) and it dis the job, but I've never been happy the way it works and it's lack of integration with the Sat Nav monitor and MFSW. As I didn't fancy paying a dealer £120 for the harness, I started looking on the internet about a DIY custom solution, an OEM ULF with a custom harness, after all the OEM ULF is just a BT module with an I-Bus interface, right. I found loads of info about the module and the pinouts for the 54 Pin plug and someone who had already done it, a Spanish guy on a Spanish bmw forum, (thanks micro088). So, I'm in the process of custom retrofitting the OEM BT setup, I reckoned, that I could do the whole thing for less than the price of the parrot (3100 or 3000) plus the connects2 box and leads, or the New nokia setup. It Looked like it was well do-able. Since my car has the 40 quadlock and SatNav, custom making the 54pin ULF harness was very straight forward, here is the 54pin pinouts. Pinouts ===================================== BM54 - Main, 16 Pin Quadlock Connector X13646-10----------------------- MUTE -----------------------PIN 51 ULF X13646-12----------------------- GND ------------------------PIN 36 ULF X13646-15----------------------- +12 V Perm----------------PIN 17 ULF X13646-16----------------------- +12 V Switched------------PIN 35 ULF X13646-9------------------------ I-BUS -----------------------PIN 15 ULF X13646-11----------------------- TEL ON ---------------------PIN 33 ULF BM54 - Small, 12 pin connector (C Btm right) X13649-6---------------------- Tel Audio Out + --------------PIN 37 ULF X13649-12--------------------- Tel Audio Out - --------------PIN 38 ULF Extras, MIC: MIC + ----------------------------------------------------------PIN 1 ULF MIC - ----------------------------------------------------------PIN 19 ULF MIC Shield-----------------------------------------------------PIN 21 ULF GND-----------------------(Pairing switch)--/ ----------------PIN 32 ULF Eject box, 18 Pin elo connector ===================================== Pin-7 Pairing Button------------PIN 32 Pin-8 12v+ ign Pin-10 12v+ Pin-17 Ground. So once I'd made my mind up, I started by getting the 54pin plug from the dealer, as it was on back order, I looked around and came across the same plug used by Audi for there BT module, I ordered the plug and connectors, and they were here within 3 days. 54 Pin connector £1.47 Audi Dealer - Audi p/n 4e0-972-144. Pins for connector £0.97 ea (x10 = £9.70) Audi Dealer - Audi p/n 000-979-010. Got a BT ULF, 12th Gen with Voice control Several things of eBay: Telemute Harness--------£9.50 Pair button ---------------£1.30, I didn't bother with the eject box as the phone is always charged and BT enabled. Leads (Mic & Switch)-----£4.49, used 2.5mm speaker lead. (as they don't have to carry any high volages, I thought this would be OK, and it seems to work OK). Then I made up the 54pin plug. Cut and modded the telemute lead to include the ULF connectors and soldered and heatshrank the joints, followed the pinouts from the radio module and ULF (this is just an example). I had to get several bits from the dealer (its hard to believe but they were cheaper than eBay) Antenna, antenna fakra lead, antenna bracket and mic. Plugged in to test, and the satnav detected the BT module straight away. Then selected the phone and go through pair process and bobs you uncle. Total outlay is approx £180, sound quality is much better than that of the nokia kit and I now have full integration with the MFSW/ Satnav display, as well as voice control, the phone book has transfered and you can use the buttons on the display to call and receive calls. Well pleased with the results. Link to comment Share on other sites More sharing options...
