I ordered a Tundra CrewMax Limited 4x4, sunroof, nav., 5.7L, tow package, and sonar on 2/28. My dealer just called and it is due to arrive NEXT week! When I ordered my truck in Feb. I was told that if I ordered a 5.7L engine that I had to have the tow package back in Feb. I was just told that since then that the order configurations have changed from Toyota. Because of dealer and customer input that if your truck has the tow package that you CANNOT get sonar! Apparently the tow package and sonar was a problematic combination. Has anyone else run into this problem? I have rear sonar and a tow package currently on my Ford. I really had wanted the sonar for parking and putting it in my garage.
