I made the mistake of allowing my dealer to implement the "free" GPS upgrade for my 2004 ES330. The upgrade is actually a downgrade. I found by speaking with Lexus customer service that the company has changed suppliers. The new maps are worse, not better than the ones they replaced. In fact the new supplier has the same terrible maps as MAPQUEST. How do I know? Because Mapquest.com has precisely the same mapping errors that plague the navigational guidance in my car.
To add insult to injury, Lexus customer service tells me it is "impossible" to go back to the better, previous system. I'm still working with my dealer to get a different answer to this request.
So if you haven't yet accepted the free upgrade, think twice.
