Telenav wants its latest Scout update for iPhone to stand out from other nav apps by giving what it claims 80 percent of us want while driving: gas, coffee, or food. You can now select a spot serving one of those sans typing and be sure its decent thanks to a user feedback feature that even accounts for the time of day. Then, Scout will only search places on the road ahead, not behind, to efficiently re-route you — a feature surprisingly lacking in most GPS apps.
