I had no touch screen on my first car pc. Using a front end made it easier because all the icons that you would have to click on were made big enough for a finger to press and that made them an easy target with a mouse. It's hard to click on anything accurately and try to drive at the same time.
Centrafuse is a great front end and in my opinion is the best out there. Also you can't pass up the fact that the Flux team is releasing the much anticipated Centrafuse 3.0 either today or tomorrow.
FYI... use a mouse or touchpad if you do not have a touchscreen. Almost every front end is made for a touchscreen environment.
What about use of a keyboard instead of a mouse because I would like to use the keyboard and use the mouse as less as passable because my keyboard has alot of shortcut keys at the top like volume and media player functions
he is using a program to setup the number pad as hotkeys-- giving him almost complete control over his audio playback. i think that you could use a very similar setup, you would just need to modify it to work best for you.
