Information

The LEAF’s touch screen system runs Windows Embedded Automotive 7. Windows Embedded Automotive 7 is the successor to
Windows CE (A Technical Companion to Windows Embedded Automotive 7, page 7). Windows CE is a distinct operating system and kernel, rather than a trimmed-down version of desktop Windows.

CARWINGS

2G to 3G Switch-Over

CARWINGS in older LEAF SVs and SLs (2011-2015) works over AT&T’s 2G network. AT&T is terminating its 2G network at the end of 2016.

  • How to tell if your LEAF’s CARWINGS already have 3G: go into “menu, carwings, carwings settings, down arrow, unit ID information.
    If TCUID starts with:
  • 2012-1, or anything other than 2012: already 3G; requires no update.
  • 2012-0: 2G; requires update.
  • Upgrade path: an updated Telematics Control Unit (TCU) will allow CARWINGS to work on 3G.
  • 2015 LEAFs will get free TCU update. Part number of new TCU was reported to be 283BO-6NF2A.
  • 2011-2014 LEAF owners can pay a “co-pay” of $199 to update their TCU.
  • The update procedure, “which will take a few hours, will leave customer’s cars with the same credentials and login information for NissanConnect EV (formerly CARWINGS) as before, and should restore full functionality to cars whose telematics systems would otherwise go dark on December 31, 2016.
  • You will need to provide the Nissan tech with your NissanConnect EV ID and password. They need the credential to perform some part of the upgrade.
  • The service will continue for free, as before.

    CARWINGS

  • “Crashed the nav system: anyone else?” Interwiki: mnl++
  • Navigation & range bug: If, in plotting a route, the LEAF’s navigation system encounters an area with incomplete map information, it will not inform you in advance, so the “miles to destination” will be incorrect and you may not find out until you’re actually driving into that area. At that point, you may find out that your destination is too far away to reach with the remaining battery charge!
