Encouraged by the initial positive reports on the charger with TMC receiver I purchased the part of my GO 730T. And it works, even if not expressly provided for by TomTom's 730T. Although the cable is 20cm longer than the original charging cable and a bit thicker (2-core flat cable), but the TMC reception will also work if I have the cable rolled up and tied together appropriately. Finally also the weak point TMC jack is now no longer an issue. Many users have complained broken connectors in relevant forums. An important positive effect is probably that no further cable is (or less elegant, more or less) in front of the windshield around.
