Having recently purchased my first TomTom I was rather surprised they did not include a case, seems to be the way with most things these days! Anyway, I wanted a case to protect the TomTom when not in use, most of the cases seemed to hold just TomTom and not the cables and the official TomTom case seemed to have an issue with the zip. I wanted something lightweight and sturdy that could hold the TomTom and its cables - the DURAGADGET case is perfect for this. My TomTom GO 530 fits snugly in a custom moulded pocket and a flap then protects the screen. The cables fit in a mesh pocket on the opposite side. The case is very well made and feels like a high quality product. A number of reviews mention the cradle will not fit in the case - this is true for my TomTom GO 530 but not an issue for me as the cradle is left in the car glove box. I only remove the TomTom and its cables. I guess if you frequently use your SatNav in another car it might be nice to have a case that also took the cradle, but then you would need a bigger case.
The case was delivered very quickly and even included a screen protector I had not expected. I would highly recommend this case for your TomTom, it really is made for the job and also seems to be a better quality case for your money than any others I found on Amazon or elsewhere.
