Poor FM reception after aftermarket install

I give it at best a 3 star review. Its nice and cheap but it has some real annoyances.

Pros>
1)Really fast boot time. From switching on the key to fully ready is less than 5 seconds.
2)Bright screen
3)adequate power for stock speakers
4) Lots of connectivity in the back
5) Fast charge usb port
6) Well marked cable harness

Cons>
1)Sometimes I have to touch 2-3 times to register my touch
2)FM reception is not good
3)Would rather have a volume knob rather than touchscreen buttons on the side. It takes attention away from driving to change the volume. Half the time it doesn't "see" my touches.
4)It might have "too good" of a resolution. Aside from the main screen icons, everything is tiny on the screen. Especially text in apps is very tiny. Not great for someone who need bifocals.
5)When using google maps for navigation, the first second or two of the verbal directions are always cut off, so instead of hearing "in 500 feet, keep left at the fork." what you hear is "...at the fork." which is really annoying.
6)Backup camera shows "lost signal" every now and then if you put it in reverse just after turning on (like most people do). Video is not smooth but "hiccups" a bit.
