I have just purchased a Android 7.1 radio for my car - I need a map card not a phone for the navigation. Pumpkin who are sellers of these radios will supply a link to iGo maps for free so ordered it and here it is Thanks for your purchase! There is no SD card included in the package, hope you understand. You can download google or waze map software or other navigation app. If you want to use the offline map, you can download the map software from this link: https://mega.nz/#!Jc0XnSgQ!m1wI4_byJ_Tvekq_MN_R-gjwCZgHBHi3aOxOK07rBEs Please download the map files, unzip it. Then please prepare an empty SD card (8GB), and then copy all the files to the SD card and inset it to the GPS card slot. Then pls go to EOM--APK--GPS Card and you can install the IGO map app. Best regards! Now my problems started - Clicked link and message came up "Cyberfox does not have enough memory use Chrome" - downloaded Chrome and clicked link - Took hours but finally got link into my download file. I then downloaded WinRAR to open file - No Luck - I then clicked link and opened it and it installed MEGAsync (Kim Dot.Com fame) - So at moment I can find the file to open but no idea how to get it in WinRAR - If I could I can probably work out the rest but at moment things are very close to being thrown out of the window. In a nut shell I have absolutely no idea what I am doing except poking and hoping which I have to admit works most of time. I am at the point of uninstalling everything that had come in and deleting all of the files and starting again. I hate these stupid senior moments..
