I just purchased an '08 Toyota Tundra Double Cab. The main purpose is going to be for towing and in the cab will by my wife and 3 boys. I have a limited amount of funds to play with and already want to get a hard tonneau cover so..... My want list is as follows: GPS Nav system - looking at the Pioneer AVIC X920BT (I do have a 3yr old portable unit for the meantime) Integrated Blue Tooth and iPhone Backup camera Head Rest DVD units. Based on all the above I know I am going to be a bit short on the funds so for the time being would you recommend: 1) Just going with the Dual DVD head rest units and waiting on the head unit and other toys for the time being. 2) I can get the head unit now and the cameran/iPhone, but the Head rest monitors will have to wait Keeping the kids occupied on long drives is very,very,very, important.
