| Nav system manual entry is disabled when car is in motion. forces user to use voice commands. voice recognition is poor - has difficulty in recognizing words such as montreal, ottawa. street names have to be exactly for exampe avenue main, if main is said it will never find it. does not have the option of selecting intersection when driving. all this make the nav system a safety hazard. driver becomes distracted trying to get the entry into the system. slows down, drifts in lane. this is more dangerous than allowing the driver to enter data manually. there is an after market over-ride available - which the service manager says, if installed will not void warranty. but from a safety perspective, lexus should offer a usable system or refund users their monies and disable a dangerous feature. | |||

| Nav system does not distinguish height on highways. this is very dangerous on elevated highways - as nav system asks driver to take exits that don't exist. as a result will cause a driver to panic - leading to an accident situation. nowhere in the advertising documentation does it state that it cannot distinguish elevated highways and side roads. lexus charges a premium for this device and it is a safety concern to drivers unaware of its faults. moreover, there should be a way for car companies to be accountable on the quality of electronics they deliver. a notice to all owners with the nav system should be sent out. car dealer acknowledges nav system deficiency. no fix available. substandard product for a lexus automobile | |||

| Navigation system does not identify poi's such as gas stations along route. this is dangerous as when the nav system is used as a primary info source - looking for a gas station, one cannot be found. leaves user in a panic state - which can lead to dangerous situations. lexus - sold an integrated nav system - which is supposed to be a reference when traveling. this reference is un-reliable and should be recalled for a fix as a safety issue. discussed this with sales person at dealer, acknowledged verbally that the nav system has problems - no upgrades available | |||
