Thanks Funpig, I think my Galazy S2 requires the Internet access as when I try to respond to a text with voice or simply bring up the google icon with the microphone it tells me I need a connection.
But the Garmin will voice dial t fine so it must have its own built in voice stuff. I have a $30 LG flip phone, no voice support on that one of course, and I am going to put the SIM in that and see if the Garmin can voice dial that one.
If it can then I know that everything is in the Garmin as the phone has no voice functions whatsoever.
I was planning on getting the Jabra Journey anyway, so as you say I can just try it. I think that Parrot does make some with what I want it do do, but their reviews are not great and the standby time is not even close to what the Jabra is, which is up to 1000 hours, has the auto connect and disconnect, etc. I want something (not too expensive) that I can leave in my car all the time and not have to worry about turning on and off, etc and if it gets stolen it won't be a huge deal.
