That's a complicated answer. A dealer can order the sonar without the navigation. That is the easy part. The hard part is getting the order approved and actually built. That's because of the unusual way Toyota takes orders and build schedules. Your regional distributor may have ordered all trucks for your region with both options. If that is the case, a dealer can take one of his incoming units and request that the navigation be dropped in favor of another audio system.I've been told that the factory installed Front and Rear Sonar option is only available if the Navigation option is also ordered?
Do any of you have the factory Sonar option without the Navigation option?
