GO720 iPhone 4 w/ tether plan

Jul 29, 2007
I have a TomTom Go 720 and I am attempting to connect it to my iPhone 4 to access data. My iPhone 4 has the optional bluetooth tethering enabled on it and I can access internet just fine while tethering it to my laptop.

When Pairing the GO 720 with my iPhone 4, it doesn't detect a data connection when tethering is enabled.

Any way I can get the TomTom to access data over the iPhone 4?

The iPhone doesn't support the Bluetooth DUN profile which is needed by the TomTom in order to access the data connection which is why its not working. Not a lot you can do about this I am afraid other than use a different phone that does support the BT DUN profile with a Pay-n-Go SIM card fitted - Mike
