The form does not specify the dimensions, so that you must rely on the GPS of the photo to appreciate the size. The dimensions are 15.5 x 13 x 7.5 cm. The bag is suitable for the TomTom XL (not One as shown, even if he returns -there was an empty half of the width of the GPS, but it is kept after closing the case and does not move). The bag has a background that will put the GPS (only for XL), but it must then remove the EasyFix support, which must then be placed elsewhere (where?). The bottom is unnecessary and remove. With fixation, height is tight, you press on the top of the bag to close it, but it allows a good maintenance of GPS. By cons, no place for the documentation of the GPS, though small, but we can find him. The case is solid. Contrary to what is said in a commentary, the zipper is metal and looks solid. For cons, I confirm that there is no marker to detect the top, so that the GPS can fall opening (it is just laid, not maintained by any system. It can locate the top bag by the position of the strap). It is small, and the strap allows easy transport, unlike the TomTom bag, too much for my taste for those who want to move with his GPS. The top thread will place the power adapter and USB cable, but no more (possibly a small power adapter if you have a TT One, placed in the compartment GPS)!
In conclusion, good product, but which deserves a GPS attachment system and a few millimeters more in height, and possibly 2/3 mm more in depth to be able to place the doc as GPS.
