I am a little dissapointed in the voice nav. on 930 The new garmin's let you say anything that is a choice on the screen, and you can do anything without touching the screen. The 930 is very minimal. However, since it CAN do voice rec. , do you a think a future software upgrade will make it much better? Or is there any third party vendors working on this? I ask because I am considering getting the garmin instead.
