Hey, took my car in for a tsib and got a IS with nav. Might be a long shot but was wondering if there was anything one can do to get the resolution on the GS lookin like the newer navs? Thanks
Only way I know is change the navigation unit. It's a whole package.
I asked my dealer, and he told me this same answer. I did update the maps, which improved the interface on our 07, but did not change the interface on the 09. At least no more AGREE on the 07!
