Has any one ever tried to run an IPad off their TQI radio?

Obviously it wont fit in the dock but has any one tried to use an extension cable to plug their IPad into the radio?

Reason behind this:

Just purchased a DTS-1 system and thought it would be easier to use the app on a IPad so other people can see it. I don't own an IPad nor would I go out and buy one for JUST for this purpose. Essentially the idea is to have many people be able to view their information such as speed, time, R/T, etc... instead of some one constantly looking over your shoulder at your radio.

Thoughts? Input?
