Just purchased a 2005 GX. If I upgrade the Nav software, will that improve the screen resolution? I was in a 2008 RX today and the maps are much crisper than the '05. Thoughts?

No dice. The better graphics is from the higher resolution screen found on the generation 5 systems. The screen in your gen4 system is incapable of produching those high resolution pictures.

Thanks much for the response; greatly appreciated.
