Lexus RX Bluetooth Pairing Failure

My 2017 Lexus RX, gasoline engine, with 141840 km is failing to connect with my smartphone. There's a stored error too. I've restarted the infotainment and checked Bluetooth. Any known pairing issues or software I've missed?

Bluetooth gremlins, eh? Have you tried deleting the phone profile from the car and re-pairing? Is your phone's OS current? Sometimes those things cause headaches. Any other functionality affected?

I've re-paired the phone multiple times. Could outdated software on the head unit be the problem, even with the phone OS current? Should I do a full system reset, or get diagnostic testing?

A full system reset could work, but with persistent pairing issues and a stored error code, it points to a deeper problem. Your RX probably requires professional attention. Are you prepared to start tearing your dash apart, or would you like a professional to have a look?

I brought my Lexus to the shop. The issue was an incorrectly paired device causing a software conflict. The repair involved recalibrating the Bluetooth module and clearing the error memory. Total was 45€ Thanks for the pointers!
