The wife's 2009 Honda Pilot does not have a grid on the back up camera.
I cannot really say I use either one the cameras 100% of the time when I'm backing up.
The Pilot has the Proximity Sensors and I do wish that I had those on the Mazda.
Kinda wish the mirrors would pull in like my Truck does, when I push the Mirror adjust button.
This would help with Car Wash's and such.
I think my biggest complaint with the Nav is the lock out but I will get used to setting my destination in before I leave.
Would be nice if I could program a trip on my computer or tablet at home and then bring that trip to the car with all the points I want to stop at.
Wish that when you are streaming music (Pandora) from your phone thru the bluetooth that the song would display, this is most likely a issue with the protocol used for the link between the car and the phone, but would be nice.
Only Seven years and 11 months until I buy another car, so I got time before I have to look.
Just purchased 2012 GT CX9. Major issue I have is there are no backup grid lines on the backup camera display. Basically backing up without the line images is a pain. Makes the camera useless. I have driven many many cars with a rear view cameras and this is the first I have seen without the screen image. 2011 CX9s have the image, 2012s do not. Mazda says the tsunami caused them to source the camera from a different supplier. I want a RECALL!!!!
