I cant seem to find any info but is there a way to download the maps or somehow use the maps from the TomTom 1.4 + maps download with this as I am using it with my Android head unit and I dont have time to let it download 5gigs worth of maps for the USA and I have to rely on wifi as my head unit does not have any kind of network service so letting my vehicle sit in my driveway with it turned on for hours while it download is not an option (Dont have the fastest internet out in the country). Would love to be able to download it on my computer then just transfer it with an SD card or something.
