well, it's >10yrs after the initial post, so i'm not overly confident that anyone will ever read this on the engineering team... but yes, would be great if as i zoom in, the text didn't stay the same overly small size but rather enlarged so i could read a given street name i want to see in detail...

I have 9 inch (1280x720 - 160 dpi) head unit in my car. (Teyes CC3)
Some element in the gui looks too small and hard to read and interact with.
E.g:
1. Speed Limit icon - so small.
2. Status bar - too thin.
3. Update Icon too small + Inner menu like hazard to small to select and identify while driving.

Please apply fix for the gui to make it easier to see and operate on this resolution.

I must agree with this comment as I believe that attempting to read a message on my Ipad 4 screen mounted on the dash could lead to serious distraction resulting in a potential accident. Text should be legible clearly from a distance of 1 meter or so. Either have a zoom feature when tapping with finger on the text or offer various text sizes as an option.
