Radio navigation system MFD
The Radio Navigation System MFD , or MFD for short, is a car navigation device that is installed by VW , Seat , Škoda and Ford , among others . It is based on the technology that is also used in the Blaupunkt devices of the TravelPilot and TravelPilot DX series . However, it is installed like a car radio, so the monitor is in the same unit as the radio part and the CD drive.
Technical
MFD is a car navigation system with a 5 inch color screen and an integrated radio receiver. The device is higher than normal car radios (2 DIN). The CD drive is not able to read music CDs, although this would be technically easily possible if the map data were transferred to a sufficiently large main memory after the route was calculated. Playing music CDs is therefore only possible from any music source using an optionally connectable CD changer or a line-in adapter.
There are five generations of devices, A, B, C, D and G. The generation determines which map CDs the device can process. The final digit of the part number can be used to identify which variant it is. A distinction can also be found in the software menu. To do this, press the number buttons 3 & 6 on the MFD at the same time and look under "NAV HW": 102 means A or B, 1001 is C and 0102 is D.
As a rule, MFD cannot process TMC signals, but the devices of Generation C, D and G can be retrofitted with an external TMC box.
In the meantime, successor devices are on the market that work with a DVD drive, have TMC reception permanently installed and have a 6.5 "screen. All data currently available for Europe fit on the associated map DVD, so that cross-border and Navigation down to the house number is possible without changing a CD / DVD. The hardware equipment of these new devices lags far behind the current state of most portable GPS receivers in terms of computing power and graphics. As a result, the current mobile devices display the moving map on the display (Moving Map) are often much more fluid, although they usually use much less energy.
cards
The map CDs are produced by Tele Atlas and distributed by both Tele Atlas and Blaupunkt . In the meantime, the Navteq company only produced CDs for France , which were then only available through Blaupunkt.
The CDs usually contain the map material of one country, in some cases several countries are combined into one CD. Special Europe CDs are available for cross-border navigation that contain motorways and important federal highways from all digitized countries. On the other hand, the DVD for the newer generation of devices also fits the detailed high-resolution data of all the countries recorded so far, although the density of details still differs significantly between the countries (mainly Eastern and Southeastern Europe).
Generation A and B MFD devices require the "non-DX" version, generation C, D or G devices require the "DX" version.
connections
Several optional devices can be connected to one MFD, e.g. B. a TV tuner, speakerphone, CD changer and multifunction steering wheel.
FIS speedometer
Optionally, the MFD can also be connected to an FIS speedometer. This increases driving safety, as the driver can see the direction arrows directly on the speedometer in the middle and does not have to look sideways at the navigation system. Communication takes place via a three-wire bus that connects the MFD with the instrument cluster. Version G is an exception, in which the suitable speedometer receives the signal via the TMC box via the Comfort CAN bus.
