I went ahead to just get a cheapo typical fakra usb cable and plugged into the MULF2-HI. The cable will be in the trunk and the USB thumb drive will be there as well.
Also, since my radio's software is from before USB was even available, I had to update it so I asked for help on this forum. http://www.e90post.com/forums/showthread.php?t=1207697
Ok, cable plugged into the MULF2-HI, radio software updated, went to NCS to code radio, 'aktive'-ed 2RAD_USB. USB icon is now on the radio. Here I'm almost already celebrating but little did I know what's about to come.
Happily I went to plug in the pen drive expecting to now listen to my mp3s on it. Went back to the car, USB icon still "- -". Started doubting many conditions such as a dud cable or what not. Did things like shaving off the legs of the cable hoping to get a better connection. No go, still "USB - -"
Step 2 of troubleshooting, plugged in my INPA cable to the USB port. The cable's LED lights up. Confirmed the USB connection is ok. Scratching my head again.
Went back to look through more coding, both on the 2RAD and 2MULF. Nope, all looks good... what's wrong?
So after going back and forth, I finally decided to take a risk. I changed the date of production on the VO and default coded 2RAD. USB is now working! Of course since I didn't want to mess my car up, I did not FA WRITE the VO to my modules. I left it and called it a day....
Hope this helps since all information on the web is quite fragmented here and there. |
Hi,
I recently bought an E92 BMW and retrofitted a MULF2 to replace the dead MULF. Thanks to your guide I have it installed and Bluetooth is working.
I am in the process of trying to get the USB drive to work. I have tried following the posts you linked to on updating the radio software using WinKFP but can't get my head around it, including where to get the appropriate radio software version from.
I have WinKFP but don't want to risk rushing the task and ruining my radio. Can anyone please advise what I need to do here?
Once again, thanks a lot for taking the time to post all that you did. It means 12 year old cars are still being retrofitted!
