The Systafex Navi bag I bought 20 M for the TomTom Start and for which it fits perfectly. They can be closed well above the zipper and keeps the Navi to secure. He is protected here even against minor bumps. The case can be attached with a small snap hook or the loop also wear well. Only negative to note is that the associated charging cable no longer fits with in the pocket when Navi including non-removable TomTom feet are tucked in. So you have the cable even further this lie. A yet convincing solution for the start 20 M.
