This is very good, the best current gen GT hud so far in fact, but personally id like to see a few changes before i can say its perfect.
Refine the icons so there are no white pixels around the black silhouettes.
Add apps like Radar, Course map, Session Best and so on (maybe also a tire temp app). If you can make it so you can change which one is active on the fly like with Sidekick, that would be super handy.
After Selecting "accurate fixed position" and then deselecting, the hud elements positions should be preserved so then you can have an accurate hud with some bits placement finetuned. i find that the lap timer is a bit too in the way of my view.
Not sure how easy these changes would be but if you implement them then this will definitely be the last HUD I use
I can't give a detailed reply on a review
