The main benefit is that this allows using the phone in landscape Mode while maps car Mode for what ever reason still only works in the default orientstion.

This also Shows the current speed which is something maps doesnt do everswhere.

There is also a option that looks like the new android auto ui.

This one? Flac is split in two parts.

Found via Google, seems legit.

noticed the missing word after posting it but it doesnt seem like it can be changed after posting.

Or what do you mean?

Edit: oh i can edit it, so it just doesnt work in the app i use.

Doesnt need to be open source to share the apk

Sadly its something he doesnt seem to want.
