The navigation works well. But the firmware has errors. See also my detailed review of Nüvi 1390Tpro, this device has the same firmware as the 1490Tpro and only a smaller display. The danger warning focal points no longer causes a crash (after firmware update 2.90), and the Nuvi will now log properly and discreetly in approximation. The choice of slide show with additional images leads to a crash, manual indexing goes. TMCpro funtioniert not error-free. After a few minutes of receiving interrupts and can often only after rebooting, re-activate. This problem has been discussed by other users on the network (see link in the comment). A dynamic traffic jam avoidance function is therefore a matter of luck and practically impossible. For the reception I have tried different positions of the wire antenna.
