My navigation unit is making a bad grinding/rattling sound, like a bad computer fan. I've suffered with a lot of the 2014 nav issues (glitches etc), and now that the fan in the unit is probably bad I might end up with a replacement.

Is there any chance that the replacement unit - if the dealer replaces it - will be actually better than the one I have now? Faster and more reliable as the newer cars are?

I doubt it. Mine was replaced because the Lexus technician said that it was corrupted. It performs at the same speed, without the issues that I had before, so I would say more reliable, yes - faster, no.

I had mine also replaced because of the software being corrupted.(random reboots). The new unit is more reliable(no random reboots so far) and the speed stayed the same.

Everything stays the same with the unit minus well you know your issues lol

I had mine replaced several months ago under warranty because it kept loosing all the customized settings and presets. The new one has no issues but isn't any faster.
