 We have owned Toyota products for many years.  Our previous car was a Toyota Camry.  It had a reliable navigation system that worked consistently and was accurate.  It never occurred to us when purchasing a new Toyota Camry that we would not have an even better navigation system.  But Toyota  installed an inferior product  called Scout that relies on the customer having a certain type of cell phone.  The phone needs to actually be plugged in for a map to show on the screen.  When my i phone updated recently, the entire GPS system ceased to work.  Toyota seems to want to blame Apple for this disaster.  I depend on my GPS extensively and am devastated to be stuck with this car for the next several years.  My dealership says that Toyota's new 2019 models will not have this defective system.  However Toyota has made no effort to recall and install a reliable system.  The response from Toyota is that perhaps the Apple update will eventually synch with their Scout GPS system.  How shameful! I have had Toyota products for our last five vehicles and expect better quality and service.
