The major reason, that you probably didn't find a screen sized 3.5-4" is because of the difficulty you would have seeing anything on it. Remember those Casio, and Sony handheld pocket TV's from the 80's? Yes you could sort of see and hear you program, but only if you held it really close to your face. Even in a small car it would be beneficial to have a larger screen to see the NAV.
Most of primary Navigation Systems, by Alpine, Kenwood, & Pioneer use proprietary touch screen also, so finding one that small may have a compatibility problem. The product you hear advertised on TV by Tom Tom is available at Best Buy and it is about the right size you could at least check it out first in the store. Also Alpine has anew product soon to be released, that is also portable with navigation called the blackbird it has a 3.6” LCD screen but the device is slightly larger.
