Bought my 17 HC a few months back and everything has been great... except my screen seems to Malfunction like someone is pressing on it. Like i switch it to Navigation ,and the screen acts like i'm pressing menu or something. Another example if i have it on Fm radio and this issue happens it constantly presses FM section and i hear it beep and i can see an imprint as if it was pushed. I have only had this issues a few times haven't been able to recreate it it just happens when ever. Was wondering if anyone had this issue or may know how to fix it.
