I like sygic also, works better than anything else for us driving all over na. I have a tomtom device but sygic on the phone or ipad is more reliable. Offline use is important to me, so google or apple maps are out for me.I also like Sygic navigation. It works offline, have always updated maps. Best GPS app for smartphone in Canada for sure.
