No offense. I think mobile phone shots cannot make it (even with Nokia N-series).
Good photos with sharp wordings, clear signage and overall brightness (daylight) is essential to produce good JCV graphics (using automated tools or manual human work).
Thus, I strongly suggest using an above average digital camera (not those mobile phones) with at least 3.1 megapixel, set to maximum resolution to take the photos.
Your photos suffer from low resolution and poor focus. If you are taking the photo on foot, the best is to use a DSLR and a tele-zoom and shoot for further away so that the whole junction can be captured in a narrower angle to fit the GPS screen. If taken from the car, the best you can do to ensure sharpness and sufficient resolution is to use a good compact camera and select the resolution to between 4-5 megapixels. You can always do PP and resize later.
My experience shows that the windscreen does degrade the picture quality quite substantially when shooting from inside a car, even with good DSLR.
The final product is a small image of 210x190 pixels. Glancing at it from the driver's seat, nobody is going to notice the difference in picture quality. At this size and the short moment of looking at the picture, we found that shapes, horizon/building line and color contrast play a bigger role in conveying road info.
