Anyone have your "maintenance required" light come on around 4,500 miles? I thought it alerts at 5000K. Regarding the navigation system, I bought my '05 prius with everything on it except navigation. Anybody buy one aftermarket and have it installed and for how much? Thanks for your time....
The light comes on 500 mi. before oil change is due and then goes out after a little while, when it hits 5,000 mi, it stays on steady till you reset it.
