I have an 07 G35X that I purchased new. I had been noticing more and more that the GPS was 'missing' a lot of the places I needed to go for work. I was going to upgrade in November last year but my Service Manager said to wait for the '10 - '11 maps to come out on Dec 6th. I waited, got the new maps, and.... to be honest it's a mixed bag. On the plus side several of the addresses that I need for work are now included in the maps that were not there before. On the downside some of the addresses that are at least 2 years old are still missing and for some strange reason my house, which was a couple doors off on the maps, is now over a block and 1/2 off... not sure how or why that changed since the house hasn't moved in 18 years (well not for the 7 I've lived there anyway).
I can't say much about the restaurant look ups since I rarely use them.
Was it worth the $200 it cost for the new maps and install... for me, yes. Since I drive to new locations all of the time having the maps as up to date as possible does help. I won't be upgrading the maps on this car again, the next map update I do will come with a whole new car as a bonus
