It took me a while to decide to upgrade the electronics on my car for a better cell connection. The Tesla is now 9 years old with 114,000 miles. But honestly the car is just fine and the items I am most interested in upgrading are quite small (CarPlay and a physically smaller car), or quite expensive (a giant battery giving around 300+ miles of range).

The 3G capability of the car was getting quite unreliable. About half the time it could not connect at all. At times having the traffic data on the screen is quite useful, and other times being able to find a new place on the map was helpful by name and not by address.

I was also experiencing another problem that I was informed was related to the old electronics. The car would take quite a while to wake up. Since installing the new electronics, the car wakeup time is not instantaneous but it feels faster than before. I never measured the amount of time, so this observation may be inaccurate.

AT&T has decided to completely discontinue the 3G network, and Tesla notified us that we needed to do the upgrade. I finally caved in and had the service done, which must occur at a service center. The final bill was $218.
