    Just had the MCU2 upgrade done to 2014 Dec issue S85 as after may visits and calls regarding MCU1 failing issues I just thought that I would like my heating to work, internet connection to come back on and the car to stop rebooting if I looked at it the wrong way.

    Very happy with the screen replacement and speed of interface, went to reverse into my drive at night and could not see a thing. I was literally reversing blind as the reverse camera view was so dim compared to before, sent text to Tesla services and they put out a software update but initially asked if the brand new screen interface they had put in that afternoon was really dirty and that's why I couldn't see behind me????

    But where as I had not had connectivity for over 4 months I now do, it is still 3G? Pretty sure an LTE/4G upgrade was included, wondering if they just put my old 'Spanish local' sim card back in.

    Can't log in to youtube as it says this web browser doesn't support it?

    Can't get Netflix to show properly on screen so can not log in and 3Gtoo slow for it anyhow.

    Hoping they will sort out the LTE/4G upgrade and it was just an error on their part. The 6hr wait on a stool in the waiting room and being told that it now might take a couple of days to fix and a blank stare without so much of a 'sorry we said it was an afternoon job' and now you might have to walk 70 miles to get home... I can deal with that, but Netflix and LTE/4G was a big part of the upgrade that I would like sorted.... Feeling like you have to hassle them at Bristol service centre to get any updates and that you are a pain in the butt for having this upgrade done because their MCU1 was at fault constantly.

    Sorry to hear that now you're having this issue... Have you been able to ask them about LTE? What do they say? I also thought LTE was included for the older cars.

    Mine was made in Sept to Dec 2014 so just missed out on LTE and is 3G. I have never seen the 3G change to LTE or 4G after the MCU2 update even right next to the new communication Tower where my phone says 4G full bars.

    The first S's to have LTE in the U.S. were delivered in April 2015. Yes, you missed it by 6 months.
