If you are talking about the housing, mine is the older model. 5" i think.
The touch screen i want to put inside, is 7".
Problem is in height. No matter how plastic i cut, the upper portion of the 7" touch screen will not be visible.
The newer-bigger model housing has les curve in the upper section, thus more available visible height for the screen.
no ment what type of sat nav did you buy sony garmin talk talk? as the sony nu95 fits the old style housing with a little cutting.
