I was previously using my car's built it AVT navigation system but ever since I installed Waze, I rarely use AVT anymore. Mainly due to Waze's ability to display where traffic is and provide a route to avoid it. It isn't perfect since mapping and the traffic information is crowdsourced but it sure beats my AVT and the MMDA traffic info app combined.
