So Honda/Acura have an over the air update that has to be complete prior to their 3G network being shutdown that allows the software to support the transition from 3G to VoLTE. Why cannot Toyota/Lexus figure this out?

if the problem is hardware related it can't be fixed with software update. Many of Acura models are on CDMA (3G) cellular network and they require ripping out the old hardware and replace it with a new one to make the transition.

Yes as stated the transmitter and receiver in the car itself has to be a lot operate on the frequencies of the new 4G or 5G networks. They also have to operate on the same Technology and it was not mini at all they could do both 3G and 4G and certainly not 5G.

It still seems to me that Lexus could take a thinking-outside-the-box approach to providing a solution. I wonder if they could partner with a company that makes a 3G to 4G converter to enable the modem-dependent functions to work after the 3G sunset, without needing to replace any hardware? Please see the description and video for a product called "Cellbounce" and let's discuss if it could potentially be leveraged by Lexus to extend the life of the safety and convenience features we currently receive via 3G.

I’m an RF engineer for one of the big three cellular companies in the United States. Unfortunately there’s no way around needing to swap out the module that contains the transmitter and receiver. 3G uses much smaller spectrum channels and the equipment will need to be upgraded to use the 4G technology and larger channels.

Thanks for your quick reply, Dallas250. I understand that the hardware would need to be swapped out to receive a 4G signal, but wonder about products like Cellbounce that claim to be able to receive a 4G signal from the tower and then convert it to a 3G signal locally that works with legacy 3G equipment. With your cellular expertise, I'd really appreciate your take on their web site and video https://www.cellbounce.com)
Thanks!
Thanks!

The only way to fix this problem is to replace the DCM which is 3G with a 4G DCM. Will they do it? I don't think so.
What they can do is they can update the software so it will use the DATA from the phone when it's connected to Apple Carplay.

Well, I got an answer from Cellbounce today and it isn't good. It appears that their technology would have worked but they are blocked from using it on mobile devices in the U.S. Here's the response that I got from Jim Neff of Cellbounce:
Hi Joe,
In the US we are limited by the FCC and cell providers and therefore cannot be used for mobile applications.
Sorry about that. (I have a 2014 Lexus myself)

Interesting. Is there any connected services you're subscribing to now on your Lexus? The newer vehicles are much more connected now than past generation. I recalled years ago Sirius radio came equipped in new vehicles I purchased and yet I had never subscribed once the trial period is over. Now on my Lexus I have the following active subscriptions:
1) Siriusxm radio
2) remote services
3) safety connect (SOS)
4) Dynamic Navigation
There is also Enform wi-fi but it is not active. #3 and #4 are still on trials. However once they are expired I won't be renewing them.

I have a 2016 RX and added a third party remote start by Compustar. It has a separate fob so am I good past October when the 3G disappears or is my compustar hooked up to the outdated 3G and it too will be useless? I suppose on Nov.1st I’ll find out for sure.

I get the frustration but I don't see that Lexus gains much by spending money to update the system in older cars. They are not alone. Mercedes has done little to nothing to help its customers either.
