I recently bought a 2010 lr4 and the infotainment had been acting up, Radio stations switching on its own, Bluetooth dialing by itself, voice command turning on its own, volume decreases and increases, this will happen after an hour of driving, I am wondering if this was encountered or had been discussed. Any opinions will be greatly appreciated. Thanks in advanced.

all of those things can be done from the steering wheel inputs correct? Maybe something with the wheel? Clock spring or the buttons?
That could be a possibility, but then steering button for the volume, and voice command are separate but to have both acting up at the same time is odd. I will try to spray it with contact cleaner and see if it will eliminate the problem. Is there a way to do a hard reset for the infotainment? Am I missing a software upgrade to have this problem eliminated?

seems more like spurious input, rather than software. Im not sure you can diagnose it without taking things apart.
You could just disconnect the steering wheel controls and see if that works. (not the airbag please, careful around that stuff).
Here is the service manual bits for how to get into that stuff. Don't dig into it though unless you have torn this type of thing apart before. Don't want to have you disable your vehicle by mistake. Dealer would be the way to go if you don't think you can DIY.

edit: looking at that a little closer you may be able to disconnect those switches on the column side, before the clockspring. """9. Disconnect the 2 electrical connectors from the steering column multifunction switches."""

Very interesting... Some of the steering wheel buttons on my '13 have been acting up lately, but only after pressing them. Like you, it only happens after I've been driving for over an hour or so. When pressing the volume up/down buttons, it skips multiple levels. Same skipping issue occurs when pressing the seek up/down buttons to change songs/stations. It's kind of annoying, especially when taking long road trips. My cruise control & phone/voice command buttons seem to be okay, though.
I'm curious to hear others' input.

I will attempt to remove the upper and lower shroud to access the 2 connectors for the steering controls. Hopefully I don't have to take out the steering wheel to do this, how I wish I can just remove a fuse or a relay associated to the controls.
You could try disconnecting, then reconnecting the battery. When I disconnected my battery during my install of a dashcam it seemed to reset some things inside the vehicle.

That is true, if you leave it for awhile it can reset various ECU's but I don't think the module for those controls has any sort of brain to it.. worth a try though.

Here is the diagram for the two modules. Photobucket limits quality, so sorry they are fuzzy.
Those modules have several connections throught the clock spring, so the module is on the wheel obviously and then goes through the clockspring and then also has connectors on the other side on the column itself.
It has LIN bus connections to the BCM body control module. These graphics may not exactly match, it shows the paddle shifters and heated steering wheel module also.. if you have that. But those all end up going through the clock spring connection.
