You can then just try and reload the lost map rather than go through the No Map Found process. The benefit of adding this map and leaving it unused on the device is that if you are doing an update of the Main map and you lose that because of a problem you can till start the GO5200 normally because there is a valid map on it. I mentioned Venezuela before which is a very small file. Secondly can I suggest that you add second map to your device. This may be a more stable connection for you and worth seeing if it works better for you. The connection to the PC is only as a means to connect the device to the internet. You will get a screen shot saying do the update via Wifi but ignore this and the PC but use the menu options on the GO5200 itself to do the updating. Next time if you have a PC with the TT My Drive Connect software on it attach your GO5200 using the TT Cable to the PC with the My Drive Connect Software running.
