May not be irrelevant since I do not have a LC/LX but I have a Lexus NX (same family), but based on my findings and thorough test, I have tried an elaborate phone call test and here are my findings:
1- The caller says that my voice sounded as if I am talking far away
2- The Caller says that they can hear themselves repeat as if it were an echo and find it quite annoying.
Upon talking and talking, the mic on the device is in fact located on the rear of the unit near the cutout of the speaker and that noisy fan, So if you were to mount the device flat against the dash or something that covers the rear, the fan noise will be projected to the mic and will emit a loud turbine like noise through your cars speaker.
I also find that when using phone call and hanging up, the music playing (spotify or youtube) does not emit any noise anymore whether pausing and playing again. Happened to my third party headunit also. Only way to solve this is the rest the Road Top.
The only solution at the moment which is cumbersome is to set the bluetooth device (road top) connected to the car set as for music and bluetooth phone connected to car set as phone calls only. When you try to make phone calls, only answer the phone with the call button on steering wheel and not the Road Top. If you answer by tapping answer on Road top, it will route through the devices bluetooth. If you you answer through button on steering wheel, it will route through microphone of car. When making a call, the same, through the cars phone and not through Road Tops carplay/android auto contact list. The caller says mic from stock car sounds far superior than any third party that I've tested, and that includes Grom Audio, Beatsonic and Lexion Automotive which I have tested. thought that since this device is linux based, that I can shove a usb car mic to override the mic from the device (worked on Raspberry Pi 4 running on linux with no installation needed, just plug and play) but no cigar. Reason I mentioned Raspberry Pi 4 was that I was in the process of building the Open Auto Pro head unit to test it out and found out that after purchasing parts for it, It exceeded around 500 dollars compared to Road Tops 200 + range.
Reason sharing my thoughts here is because This is the only active forum where people are talking about the Road Top device. I see no other part of forum sharing their issues or findings based on my intense google search and also no mention of 2nd Gen, So I decided to shed the light.
If anybody here has a solution to the bluetooth car problem, I am all open ears.
I have sent a video to the seller to see what they can do to help solve the issue.
