Garmin 3760T GPS What is the Best Firmware to get 3D and Voice Features.

[dmillerywg]

Hi I just bought a Gamin 3760T and I have been reading that it can be converted to a 3790 with the right firmware. I have tried loading
different firmwares and I have the ASR Features Working ( I have firmware CHN v 2.20 ) but no 3D Maps ( No 3D building or 3D Dem ). I was wondering what the best firmware is for the 3760T and also where can I get it. It seems that Garmin has removed the links to the old firmware as most links I have tried seem to go to
a Garmin Web page.

Also if I have the correct firmware for 3D it seems there are some files that need to be loaded onto the GPS to be able to view 3D ?

gmap3D.img and gmapdem.img ?



Thanks.
