tomtom go 720 and mobiles (2 probs)

Hi guys

I have a tomtom go 720. I have paired up the mobiles with the tomtom and
the handsfree calling works fine.
My first issue is that if either phone receive a text message, the tomtom
does not display / receive it.

Also, can the tomtom only download the phonebook for one phone? I added
both phones and downloaded both address books, but when I picked the first
phone downloaded and tried to make a call using the address book it
displayed the other phones contacts.

TIA
