So without installing SharkModem or some other "software" bluetooth modem on the 7290 is there a way of enabling DUN over bluetooth? Perhaps installing a different OS version or "unlocked" OS on the 7290? I'd like to be able to use the 7290 with my TOMTOM for the plus services. If you have an answer and can help please do... If your nervous about posting in public PM me or send me an email.
