This is a much cheaper option than Tomtom's case. It is however quite bulky being 150mm X 115mm X 70mm deep. It holds the tomtom but with the window mount removed. There is a second compartment which will take the in-car charger and window mount. The biggest design fault is that the item the case is supposed to protect is liable to fall out when opened as there is nothing in the case to secure it!
Much improved functionality - not as demanding on the systems resources and provides protection for up to three computers. Note however tha the 12 month update clock starts running from the date of the first installation. Annoyingly since I bought this product its price has been slashed by 50% which makes it very good value.
