I bought this car radio to replace the original one on my Seat Exeo. It took me two cables interfaces, to retrieve information from the trip computer, and another for the antenna, because in fact on my car home, I have two antennas, so it I had a cable which takes both to turn it into a cable. So at the installation, I had to spend a GPS cable, which really finds well the satellites (I placed it in the left corner of the dashboard under the windshield). And I had to pass a new micro, because it was impossible to recover those of my original bluetooth. Installation is simple, secure the bracket to the radio, and after screwing it on. It must also check if there is an edge cache to the car radio is intégère well in your car. For its operation, the screen is clear and legible, the steering wheel controls are well recovered, and the position of the brake and shift into reverse. The GPS mode is easy to use, it retrieves traffic information and indicates the route very well, and more and it is filled with European maps and points of interest such as gas stations. The phone mode works well, it gives the status of your battery, network and bluetooth signal. It shows you your last dialed numbers, your address book and gives you access to a keypad. At Multimedia, you have the option to AM or FM radio (3 levels) to a CD, listen to music via your Bluetooth phone, listen to music via USB (provided) . The buttons can be of different colors, you can enable a security mode that does not allow access to certain directories as the hand brake is not activated. You can also play a DVD, as the car is not running, otherwise the video display is off. Finally, this GPS is really perfect for its price, has a very good sound quality, has an option for a backup camera, and a GPS very good.
