Yes maybe, but then again V1.5 and other Garmin auto-routable maps loaded side by side also have issues but only with the quest, but it is a great GPS and running T4A non-routable together works fine. Finding caches in my area of SA often requires T4A as Garmap is nowhere to be seen eg Ongoye forest, Eshowe caches and the ones in Mtunzini area. Cant always stop and reload maps with the laptop and I did spend nearly 6 G's on it.
