I agree. I was aware of what the TLX system was, as I had a 2013 Accord touring, but still, you would think that after the 13' accord came out in 2012, that by the time the TLX came out two years later on their "premium brand", Honda would have listened to the complaints and upgraded the thing to be at least a little more responsive. At least it sounds a lot better then my Accord stereo did. But it does feel like something running Linux back in 2000. Besides a few minor graphical changes, the 13'-15' Accord and TLX systems are identical, and I'm pretty sure the Acura buyer expects something better in their premium sports sedan. Now even the '16 Accord outshines it - mind you if have used it, it's still not perfect.
It's only software, it really shouldn't be hard to optimize or update it. The problem is the screen, you need multi-touch screen to really do Android Auto and That other one by crapple.
