Telenav’s gas price feature allows users to use GPS to find which gas station near them has the cheapest gas. The service will search around your current location (or another location that you specify) and tell you what each gas station is charging that day. You can sort by cheapest, type of gas and/or brand. Then you can get turn-by-turn GPS directions to that station. This feature is included in all TeleNav GPS Navigator versions. Launch Telenav and it can be found under the Business Listings (POI search).

(Screenshot a bit out dated, prices are almost double that now!)
