Most car DVD player have the function of gps navigation.And there is many kinds of maps can work on this device.Normally dvd player can support these maps: Tomtom, IGO, Route 66,Papago,PolNav etc.And TomTom is the most popular one.Some android dvd player even can Support One Key navigation,support Google Map + Real-time Traffic,Support Google Voice navigation,Support various map software:GARMIN,IGO8,NAVIONE,RTNAVI,AUTONAVI,MAPBAR,GUIDER,EDUSHI etc. support self-help internet navigation: GARMIN,IGO8,NAVIONE,MAPBAR,HUAWEI etc.TomTom announced a software update to a handful of its portable navigation devices. The updates aim to make these devices more customizable and easier to use. Models include the TomTom x50-series (including the XL 350 and the XXL 550). Users can access the updates for free by connecting their devices to an Internet-connected PC and downloading the software using the TomTom Home application.Every map all have the possible for map software update.Then it needs the map company to solve these problems.And users can update the map software by themselves.Hope you know the basic steps of update the software.

In the course of our extensive testing program, we collect detailed data on the features and performance for the devices as engineers travel the greater New York City region and log hours in the lab. We also rate the mounts, looking for stability, portability, and adjustability. While this score counts for far less than the navigation performance of the device itself in the overall test score, it is a real factor for ownership. After a recent experience with a new TomTom unit, I want to encourage shoppers to look closely at our mount ratings.This is not just an anecdote. We’ve tested 28 different TomTom models recently, and the vast majority have a similar mount style. The worst offenders include the TomTom Ease, Start, XL, and XXL devices. The TomTom VIA and Go Live 1535 M mounts are similar, but they work better, because TomTom eliminated the ring that snaps onto the back of the GPS unit. The mount and GPS device are essentially one piece in this design and the attachment point is “ball-in-socket.”With a ball-in-socket design, a sphere on the mount snaps into an indentation on the device (think shoulder socket). Some such mounts use a magnet to secure the device to the mount, making it easy to remove, although adjustment can be tricky. These mounts are still compact, but seem to work better in our experience. This type can be found on the GO 2405, GO 2435, GO 2505, and GO 2535 in our ratings.

In fact, let me take this a step further. There is one mount design offered by TomTom that seems extremely clever, though in reality, it proves to be quite frustrating: the ring-type mount. This is a simple concept, whereby a circular ring snaps onto the back of the device. A second ring with a suction cup attaches at a small hinge point. The result is an adjustable mount that folds flat, leaving the device to be travel friendly and even pocketable (depending on the pocket and screen size) with the mount still attached.However, these mounts have a tendency to pop off the device and even the windshield, as I was reminded this past week with a relatively new TomTom. In the course of rotating through our latest test devices to gain real-world experience, I used a TomTom Start 45 TM. The mount simply would not stay attached to the windshield, popping off periodically while driving—a real distraction. That evening I had a passenger join me for a short road trip. Coincidentally, he is a TomTom owner, and he tried in vain to mount the device, but it repeatedly fell off the windshield or the mount popped off the device. Fortunately, he could hold it and guide me with his voice. Regardless of how good the device might be, I could not use it.

Some people say they use TomTom’s universal vent mount for their TomTom GPS, and it works great.Some people say his mount on his Tom Tom One pops off occasionally too.So do not worry! TomTom company can help a lot.Hope you know the basic knowledge of TomTom map for dvd player.Hope you can take care of this problem and solve it.And have a good jurny with the dvd player with TomTom gps navigation.
