Qt is basically unrivaled in this space in my opinion. If you really control your hardware and software, it seems like its easier for you to just comply with the LGPL requirements. You can find some other vendors for similar software with Google but they aren't as 'attractive' and 'responsive'. That being said I think IVI systems will start looking at web rendering soon if they haven't already. If the LGPL is a show stopper for you, you can always give CEF a shot to see if its fast enough (though I've always been confused about CEF because I thought it used WebKit which was LGPL)

Also depending on how complex your UI is going to be you can always take the crazy route and roll your own. If your scope is very specific and limited, it wouldn't be that bad.

Based on some quick research building CEF for the imx6 doesn't look trivial. Do you know of any devices (for sale) that do use Qt under the LGPL? Or in your experience does everyone get the commercial license?
