Sygic anyways is not as updated as Google Maps. In fact I found Waze much better than Google Maps as Google Maps is a bit sluggish on Grande infotainment.
I have also installed paid version of Sygic maps (not the one provided by TPL) but from Google Play and it gets maps updates from Sygic (while the stock Sygic maps are not linked to web), still Waze is more updated when it comes to new interchanges built in Islamabad.
Try Waze, you will love it.
