    • Thanks for the comments, Amanda. Good news: My 2018 and 2020 RX 350s including the 2023s all use 4G (as stated on the window sticker) and will continue to do so for some time in the future. Lexus monitors a lot of your vehicle functions and keeps a status of your system.  If the DCM Quits working, you got some real problem on your hands.  I'll just bet you, if that happens Lexus will get in touch with you real quick via e-mail or phone, telling you to bring the vehicle in ASAP.  That's what Lexus Enform is all about - keeping you on the road and out of the repair shop. If I could cut off the nav system, then when I say "Show Radar", I could not get the local radar map because Lexus would not know where I was.  You pay for that functionality for the first 3 years cause it's built into the price. After a few years I would have to pay for a subscription and it's not cheap. Sure hope the guys at Lexus can help you out with your Radio Frequency problem. Les,  1st Class FCC License operator
    • Bone spurs. Can't say I like those. 
    • Thank you for your input Les. I really appreciate it That sort of sounds similar to, at least in part, to what the service rep told me from Lexus. That maybe it was the SOS system communication. She said I could just press the button and tell the people on the 'other side' to disable it. ...but when I press the button it has a recorded voice that comes on with prompts saying it is disabled and to enable follow these so and so steps. That has me wondering about he Navigation system, I am thinking at least. The service rep also noted to me that 2017 and older models (I have 2015) have the internal WiFi disabled or not communicating she said because of the switch to 5G for newer models hence none of the apps work.. but something is transmitting for Navigation. Unfortunately definitely more than fears. I can not drive the car for more than an hour or two, sometimes less, without getting symptoms,. You may have hit on something when you said it is like a cell phone. I still have an iphone 6 4LTE and have been ok with that, but the newer cell phones make me sick (5G etc, don't know what I am going to when the iphone 6 finally does quit, but so far so good) If the SOS system of the DCM is already disabled then cutting of the Nav system shouldn't translate to alarm over to Lexus, would it? This is very hard for me to interpret as I am not a electronics/car person by any stretch. I just love Lexus RX for a lot of different reasons. I really don't know anything and am doing my best to understand and seek help where I can like these forums for any and all insight. I am taking it to a shop at some point too, to have it investigated but seems this is nothing anyone has dealt with. Thank you so much. Maybe others will know too and can weigh in 🙏
    • I just put a hitch on my new 460 but the 5000 lb. hitch was enough for my needs, so that was easy and inexpensive. The wiring is already in place. I found this YouTube video which might help you. Good luck. 
    • I also am looking into a capacitive touchscreen over the resistive one. Have you found anything? I found a sketch website that says their’s is capacitive but I keep getting the fake Tesla screens advertised to me otherwise…don’t want to remove my buttons, I just want a better touchscreen
