I took the leap and bought a 2009 RX350 with 67,000 miles back in the end of January. I've already done 5000 miles on it and it's been great so far. But, I have discovered that the radio has a mind of its own.
I do have an XM subscription and transferred that over from my previous vehicle with no issues.
90% of the time when i start the car for the first time, the SAT does not work and I get "loading" and then "tuner err" in the display screen.
Sometimes pushing the main Vol/on/off knob does nothing - if the radio is already ON it stays ON, or if it is OFF it won't turn on.
Sometimes I can turn the radio on/off by pressing one of the preset buttons. The tuning knob also does nothing at some times.
Sometimes scrolling through SAT1, SAT2, SAT3, AM, FM and back to SAT1 will make it work - sometimes it just turns the radio OFF.
Basically none of the buttons or knobs exhibit any consistency - they just randomly activate different functions on different days. Usually turning off the vehicle and re-starting will correct the radio issues and then it seems to work fine for the rest of the day.
I've seen some other weird radio issues reported here, but nothing quite like mine. Anyone else see these issues.
