Is it possible to get an updated disc for navigation on a 98 LS 400? If so does anyone know the cost?

I think they are going for $329. Its a harddrive based, no discs.

Use code CL911M for the clublexus discount.

Would this make roads appear like they do in the LS430? The difference is crazy from the LS400 to the LS430 in Navi-wise. The 430 thows All roads, and the 400 hardly any except for in two cities in KY. BULL CRAP
