Are we seriously trying to get Nissan to make an older car newer with the 2G upgrade, one thing a lot of you don't seem to grasp, is it's a Japanese company, that doesn't like cars older than 2 years, 4 years old in Japan is expensive to re-register, trying to make them liable for old tech is nuts, just like expecting them to do a battery upgrade available. unless gigafactory comes with something, your battery gets old/wore out, time to get a new car, you know kind of like a cell phone, did we expect the side kick to still be around. I got the letter for the 2g upgrade for $199. I'm still on the fence cause, I don't use any of the features from car wings. charger monitoring comes from a juice box charge monitor, and well, don't need remote pre cool/heating.
