I noticed that my GPS on my 2013 GS 350 would lose signal at times when I try to enter an address in destination. The icon can't be selected at times and sometimes it won't allow me to finish entering the address. Have you guys experienced this issue?

 

you can't input anything when the car is moving. lexus cars have navi lock out when they are moving

you will need to get override kit

 

Thanks guys!
