    How does the new unit work?



    • The new unit work a lot better,,,,BMW has always had a problem with the head units,,,,the head unit do so much and so much information goes through them,,,,they just fail,,,or blank out sometimes,,,,,due to overheating.,,,,,sometimes it’s a software issue,,,,,but not on this one,,,,the vehicle already had the latest software update,,,,so BMW had me replace the HU-H head unit .

    I had to take my CIC unit apart last Sunday. Wife was complaining that cd and dvds would no longer work. I-Drive display would always read Checking…. and would then read “unreadable format”. Separated the dvd/cd drive from the head unit, took apart (pain in the….), cleaned the laser surface and lightly lubed the transport rails. Slapped all back together (even more of a pain in the….) and to my surprise it worked again like a champ.

    I tried to source the dvd drive only online, but could not find one for a 2011 E70 X5. I’m assuming I can only get it by the dealer or I have to buy a complete head unit if the drive fails completely?

    Always something with this car!

    I tried updating my 2013 535i software level using the latest ISTA via ethernet, hooked up the battery charger, however I forgot to power on the damn charger. After running the update and voltage may have dropped to risky level, I got the blue screen on display, and ISTA would not continue updating. I’ve disconnected the battery for 30 mins and tried again, still same results. What can I or should I do at this point? TIA
