I really miss having the Nissan Connect. Was great when we were in the mall Christmas shopping and was able to heat the car up long before we got to it.
4G is only on the '19 and up. It was changed when they changed head unit manufacturer to Bosh.
I've been wondering for a while now if it is possible to upgrade the earlier Murano's TCU to get 4G.
So my questions are:
The easiest would be to simply change out the SIM card for a 4G card, if it's not soldered to the board. Goin thru the AV.pdf TCU section there are instructions on checking TCU functionality. Nissan's CONSULT is needed to make configuration changes when replacing the TCU unit, along with calls to Nissan's connect service and Sirus to get full functionality back.
Are the newer TCU's compatible with the pre '19 year models that allow a direct swap? Hard to tell, the Bosh may have different requirement for the audio input from the TCU. That's a hard one to answer considering they changed the head unit wiring at the same time and the TCU speaks thru the head unit. Again, it still needs to be configured by Nissan's CONSULT software.
If anyone has a solid answer, speak up. I may pull my TCU and try to pop it apart to check what's on the internal board.
Have a good day.
