it will be the same hardware and you'll have the latest software version. It seems the 2015-2016 models have newer hardware (I don't know this for fact) and don't suffer as much lag. You may notice that it's a bit peppier, but not much.

i can't tell any difference at all.

I had a 2014 IS250 with the Nav as a loaner. I could tell a big difference in lag between mine and the loaner. It was pretty annoying.

i have a 2014 and a 2015 and i swear i can't tell a difference.

Maybe I'm more sensitive than you or the loaner didn't have the latest software updates

Either way, the infotainment complaints are way overblown. It's not that much worse/better than anything else out there.

I had several firmware updates on my 14 system and they went a long way towards improving it. Still a bit laggy, but livable.

Agree 100%. In my experience it's not "useless" as many on here claim. I used it nearly every day. I would either load it through my phone before a trip, or just use the voice command on the go. Super simple.

"Enter an address"
"123 main street, seattle, wa"

I always found that to be pretty simple.

Or "find nearby Starbucks".

It always worked well for me.

And my most used:

"Go home".

it'll be replaced really soon, they ordered the part for me already.

14' with 33K and no issues other than burning through tires because there is no camber adjustment for a lowered car. Very annoying.

yep, i think the firmware updates have made all of the difference in closing the gap to imperceptibility between the two. and i agree, the infotainment systems are overblown. that said, if i could go back in time, i would still buy the cars with them. the oem look of an integrated map on the dash is great (to me).
