Hello, I want to install another radio in my car, one with Navi, Bluetooth for the mobile phone (iPhone), and screen to connect also a return camera. I also saw that the things can communicate with the vehicle electronics by OBD. For example, I came across these here: From Junsunhttps://www.kaufland.de/…/?… Priced very ok, funny only in the description that surely should be faulty fits this in Focus mk2 2004 – 2007. Mine is 2008 un d certainly has exactly the same dimensions! With the memory card slot, on the left is SD on the right is GPS. So on the left you can plug in multimedia and on the right what comes in? Navi? With the operating system is there Windows. Is that a problem? With many others it is Android. Then I would need another DAB box with which I get information like music titles from the radio station, but also better traffic information, right? Does it support the steering wheel control of my focus?? From OBD and However, there is nothing wrong with vehicle data. Alternatively, one of Autopumpkin, which costs 300 Euro, however! If you type in on the page www.autopumpkin.de Focus mk2 all come matching. They probably all have Android as operating system. These are then six different, or maybe better put three different in two different colors(?), black/silver. Built-in Navi has none at Pumpkin, right?? These devices offer Handymirroring i.e. I actually need do The Pumpkins would have, however, if you bought an OBD plug the possibility to retrieve vehicle data as well as to display errors. On Ebay you will find still a bit cheaper devices from Hikitiy, but they have no card slots. Navis do not have them either, only GPS position determination. Basic questions: Navi are in with the fewest devices, only GPS receivers for the position determination? Can ma n for the devices with card slots might save the Navi to the card? What is better/more timely, Windows or Android? And in relation to an iPhone? Be happy about all comments, whether more or less competent.
