Dice ipod text on Nav Screen??

[RacerX5(215)]

Ok I received my dice unit, install no problem. I did have a lil problem with the programming, but seems to work fine now. My question is in regards to the text scrolling across the nav screen. Small text is to small to read, so I went with the bigger text. The only thing is that it only shows like the first 6-7 letters then it freezes, and eventually scrolls thru it. Sometimes
1.Is there a way to more letters come across the nav screen? Faster?
2.If so how do I do that?
3.And is there supposed to be a text coming across the drivers dash area under the speed/odometer, or just the nav screen.
4. I cannot operate the ipod itself when its connected to the dice? Correct.

Thanks
