Aftermarket blue tooth can be done.
Personally, I’m fitting a LR4 Bluetooth one because it will go with the nearly new heated leather flappy paddle LR4 wheel I’ve got for it. Plus all wiring and control modules to make it work. Nice factory install to keep it neat.
My 3 had the suspension fault, would drop to stops, sometimes it would come back up, other times, I had to turn it off and on again.
Codes were generic “cross axel articulation fault” which meant bugger all.
It took an off road day and lots of movement in the suspension to get the cause. A faulty front left height sensor.
Fitted a genuine new one for £23. Recalibrated the full suspension with my IID tool and it’s covered over 12,000 miles trouble free.
I think 12 years out a sensor that’s lived in the front left wheel arch and done over 150+ miles to be fair enough. Other 3 are working fine so I’ve left them.
