bluetooth on Garmin

Mine was not listed on the Garmin Website and it works.

You have to try.......Garmin does not test them all...

As in...How many can you have associated with the unit that you can connect with? For example, I have my phone and my wife's phone set up. I'm not sure how many you could have set up. Probably many.
Your phone, spouses phone, each kids phone, neighbors phone, your work phone, your spouses work phone etc.
When connecting,
It will seek the last phone connected first, then go to which ever one it finds next.

OR...how many different phones (brands, makes, models etc) are "compatible" with any particular unit.

Blue Tooth is a major problem with cell phones. Not all cell phones are using the same software with Blue Tooth. Some phones will work, others will not. Garmin is working hard to get as many phones compatible as they can, and there are many phones being added daily, faster than we can add to the website.

If you have a phone, want to make sure it works, call Garmin to have the tech check, or take it to the store and see what gets recognized. You can do a search for phones on the unit and see what it finds.

TRIED AND TRIED AND FINALLY WENT TO THE MANUAL AND DID SEQUENCE THEY SHOWED AND IT SOMEHOW WORKED. STUPID ME. It was with a TREO 350 which they don't list. Good luck!

I have my wifes Sayno phone and my Samsung paired. lsmonop is correct about the order in which a phone is paired.
