I tried hard to enable voice command on my garmin 3790 which is upgraded to 34xx. Even after installing second time I still can't enable all the features. I cant enable 3d features,exit services,voice command,mp3 player...In the orginal version i.e nuvi 3790 I have 3d feature and voice command but after upgrading to nuvi 34xx I can't see those features. the most important of all voice command.I tried to update ASR files with mapupdater but nothing happens so I downloaded unlocked asr files for 34xx but still no result...
When I checked the backupdata (this is the data in the GPS when I bought it), In .System/Diag/ folder I don't see any html folder including supportedfuture.html file. I think the files I got from Garmin were not in order/corrupted.
Now interestingly I was unable to enter preboot mode for downgrading to 3790. But my device is not bricked because the device is working with 34x firmware but with out all features.
