The font size has been reduced in several places (nav search results, txt messages), and it's a problem for me too. I can see the things, it just takes more effort and distraction. It's crap. It's all crap. The crap is *everywhere* in v11. The changes made to the bottom bar is the biggest problem (IMO), but definitely not the only problem. Every single thing in the UI seems to have a handful of regressions.
At this point, the only thing that would "fix" it all for me would be upgrading us to v10. It's like they took v10 and made a bunch of bad changes to it... so the fix would be to revert every single change. Turn signal cameras, Sonic, and light shows can all go too. I'd like v10 before they ruined the climate controls (mid November). Then give me better manual wipers and disable OTA updates permanently.
