Hi everyone, been reading threads here for the past hour and am finding a wealth of useful info. So far, I've had the 720 out of the box for a little more than a day so I'm about as green as can be. Of course I will continue to read but I do have a couple questions...\r\n\r\nI am able to use the headphone out to route mp3's to my car audio system, but the directions only come out of the 720 speakers... any way to mute the internal speakers when the audio out is being used? Also, I'm finding that the 720 is not speaking road names... do I have to use a certain voice for text-to-speech to work? \r\n\r\nThis is my 3rd gps (had a mio 310x and a navigon 2100t) but this is by far the most advanced one. I've replaced the others for various reasons, but the main goal in getting this was a more useable mp3 player and better directions that the MIO was weak in. A bigger screen and bluetooth were important also, so I'm pleased to have these features. If I can get VR to work, that will be a huge bonus! But one step at a time.... \r\n\r\nThanks to the contributors and mods!
