Hi Ballebar,
I like you post.
I spent part of last night trying to to just that. I have a 3750. I changed the GarminDevice.xml to impersonate a 3790. I was able to register it in My Garmin and download the free maps, but for some reasons, I cannot get the 3D Building maps. The myGarmin Agent does not recognize the device enough to add all the missing files either.
Today, I tried also to change the prodkey.bin files in the .System folder without success. The myGarmin Agent does not see the device as valid for update and suggest the WebUpdated instead (which does not work either). I am probably very close. I just read your post and now I am convinced it should work. I am missing something.
What I have done so far:
- Changed Garmindevice.xml to add a valid ID for the unit (an unregistered one as well!).
- I updated the maps (I have seen all that went thought the %temp% folder EXCEPT no gmapd3d.img which was the point of the exercise). I did this twice without success and it took part of the night!
I like the idea of using a USB key. I would appreciate a lot if you could provide more information about what is really needed in the folder tree.
I am trying to convert the 3750 into a 3790. I know it will miss the voice command (except if I can solder a microphone there) and the bluetooth, but 3B building should work.
Thanks in advance,
Turbo
Edit: now that I think of it, I may have seen the gmap3d, but thought it was one I d/l from the web... I did too many things at the same time.
Edit2: After more research, it seems myAgent refuses to update because some information from the 3790T is not included in my GarminDevice.xml. Maybe a missing file specifications or another similar definition. If anybody is willing to send me a GarminDevice.xml to turboccc at hotmail dot com, I could share my results with all of you. Be sure to remove your ID from the file. Put zeros instead. Many thanks.
