Why does the Z-N326 not offer the official ZENEC navigation package in the delivery scope?

AW: Mainly to give the customer a choice, depending on his personal preferences of use. Depending on personal requirements and frequency of use, it may be sufficient to use the smartphone’s own map App via the ZENEC Smartlink Direct function (Google Maps or iOS Maps are both suitable). The smartphone Apps may offer a route guidance good enough to cover sporadic router guidance use. For customers seeking a more professional navigation system offering a wealth of comfort functions, the Z-N326-SDFEU navigation package is the better choice, since it was specifically developed for the Z-N326 unit.
