Re: t32 aftermarket gps headunit install Oziexplorer can do everything your asking.
I haven't installed it on this unit but I have a hilux that runs a wince unit that I use regularly.
You do have to purchase the ozi app and load it. Then you have to track down some topo maps. There's plenty available for free on the net if you look hard enough.
Re: t32 aftermarket gps headunit install The breadcrumb trail can be turned on or off in ozi. It is blue trail from memory and you can choose distance refreshing or time. And you can download it and then overlay it in Google earth to review your track.
Re: t32 aftermarket gps headunit install Still working fine. Its my wifes car that gets driven daily. If there was a problem believe me id hear about it.
