Please, if anyone has a BMW Blitzsafe adapter for sale, I would be very eager to chat. Mine fritzed (my own fault - I foolishly tried to build my own cable without knowledge or tools) and I miss the convenience of using my steering wheel controls with the PB. I really do not want to go the DICE route - it just seems so flimsy after the PB.
Blitzsafe still offers it - click
here. You'll need to open the box and re-solder one jumper:
5o o=o12
Re-solder it so the center pin is connected only to 5 instead of 12:
5o=o o12
The cable isn't available new. You can buy the parts to make one - the info is on the Wiki here. I've made 3 for various people and I'd PM you with a price, but I'm leaving for a month-long vacation tomorrow. Blitzsafe can also make a cable, but the one I saw didn't work and wasn't constructed well (it didn't work because some of the pins were shorted to each other).
