Upgraded from TomTom One to Go 720T in January, 2008. Both were compatible with my Sony Ericsson K610i. Subsequently upgraded my mobile phone to Sony Ericsson K770i only to find

that it wasn't listed on the TomTom site as being compatible. Only difference between the two phones being that the K770i has an FM Radio. The phone recognises the TomTom but the TomTom can't find the phone.
I am assuming TomTom do update new mobile phones, but is it best to send them an e-mail or just sit back and wait?
Have to admit I was very disappointed as I found the Go 720 great for reading out my texts as well as being able to use for hands-free calling and am missing these facilities aleady as I am a Van/Truck driver.
Any advice?
