Lexus IS250 New Navigation Map Disc May Correct Navigation System Problem
Lexus IS250 Problem

I can count the times that I utilize my navigation system and one day, the system completely froze. i took it to the lexus dealer who told me that I must buy a new navigation system for $2,000 as lexus does not repair that component, but replaces it. I can't imagine why a barely used navigation system would go out. The repair is very costly.

Entire navigation screen went out. Was told an electrical problem.
