Lexus Premium Navigation System

Recommended Posts

Is anyone else having problems with their Premium Navigation System on the NX300h? I usually set the map scale to 50yds, but when I start the car the system randomly changes the scale to anything from 100yds to 0.25 miles. In addition, the system can take anything up to 2/3 minutes to put the pointer to the correct position on the road and occasionally shows the pointer anything up to 2 miles from where I am. I took delivery of the car last November and my dealer has already installed two updates without any success in remedying the problem.

Can you display how many satellites the system is seeing? Slow and/or inaccurate positioning is usually down to GPS antenna problems

Does sound like a GPS antenna problem. Ask the dealer to check it out.

Mine started wandering about recently - maybe started about 4 weeks ago - with the car’s position about a mile out.  After a couple of miles it would lock back on.  Doesn’t make any difference as to whether the car is navigating to a location or not.
