"Beautiful, but bad engineering on the navigation."1.5 starson by ddecremer
Pros: Nav maps on hard drive, great sound, decent-sized on-screen buttons to easily select, available accessories
Cons: Buttons located on the right side of deck, Nav system is connected to the speed sensor wire -> VERY poor design back in the engineering department that came up with it!
Summary: This is great as far as an audio/video system. As stated by CNET's editor, the buttons on the right side of the deck are not convenient for the driver. I have a difficult time seeing the screen on sunny days, despite it being in day or night mode (auto mode has never functioned for me either) and/or tilted. I am a Nav Electronics Engineer for marine vessels and I am HIGHLY disappointed in the GPS function of this deck. I bought a new 2007 Mazda3 and had this deck installed. I started driving around and testing routes and such. When I would stop at a red light the car on the map would continue to move forward. When I had a route planned, it would think that I missed my turn and recalculate the route. I would make the turn that I was supposed to take and it took at least a minute each time this happened for it to relocate my actual position. VERY unacceptable when you have a lot of close turns and it is spending time calculating new routes and where you actually are. GPS systems get their movement and location data from 30 different satellites, not the speed sensor wire in your car. I came to find out that they had hooked it up wrong and that they tapped in to the tachometer wire instead by mistake, which is why the car on the map would keep moving even when stopped. Regardless, compare it to a portable GPS unit. In order for it to work you would have to connect it to a pedometer when hiking through the woods for it to know that you are moving. Unacceptable! That is the satellite's job. I am having it swapped out (for free, thank goodness) for a Kenwood DDX-6019. Very good reviews on that one.
