Got off my lazy butt and called AudioControl today. The LC6i will indeed work with Toyota's newest Entune system. Rep seemed to think they are all the same, no idea if that's true but, there's got to be minor differences between vehicles shouldn't there be?
For anyone looking for something like this, AudioControl has confirmed it WILL work, giving you pre-amps from the stock Entune HU and keep all the steering wheel controls functioning.
Next question is the far worse and involves how to actually remove the dash, get to the HU, and install the module. Figure it prudent to wait till I'm behind the wheel of my T4R before researching that though. Had hoped to buy my rig a in little under 2 weeks but the buyer on my house decided to drop out
We're supposed to get up to 10" of snow here in NOVA tonight so I'll get to see how the GX performs.
