DUDU-Meng the most annoying of all of it is linear volume control.
"closed" test group means that noone can verify from users who had external amps, who didn't, etc.
Imagine this. Linear volume control. Dudu connected to external amps with power of 1500W (combined all amps, that's value in my car, some people have more). Volume control is max 36, so let's assume 1 bar on DUDU is roughly 2.77% of 100%.
Play music. 0
0=0 W
1= pumps already 47 W into the speakers with 0dbfs.
You get the idea... As I said, audiophile forum users called this idea of linear volume control "insane".
At least give people choice, a small flash file or something.
Regarding navi bar
I also use 9.5 inch screen. I'm a grown up man and my finger covers TWO at at least icons if I want to press something.
I don't know, if you're doing it on purpose, because I can count dozens of posts here where people complain about icon and navi size. Maybe attach a stylus to every Dudu unit so people can press on the navi bar? I don't know. Or make navi double the height and decrease number of rubbish there and space it properly. I get it, it's your product. But maybe it worth looking how it looks like in any other unit (including mekede) and get to admit Dudu is the most ergonomically screwed up UI out there? Do you think buttons on competition units are big because they're blind or maybe because in the car someone has to press them without having accident? Heck, even take a look at stock FYT status bar. Navi icons on it are double the size of Dudu bottom navi.
