Ok this may be a really dumb question but I am totally new to this. How exactly do I "Open the "ttgo.bif" on your device"??? I haven't a clue how to do that, I'm sure I sound like an idiot but oh well.
I've really got no idea what I'm doing here, but I've been given a Tomtom GO730 with Navcore 8.413 installed on it and I just want to get the official version (8.351) on there instead!
Thanks so much...
