there should be settings in your HU that you can adjust to prevent this from occurring.

also, have you contacted the manufacturer of your HU?

have you went to their site to see if any tips or troubleshooting information is posted?

have you smoked over some of the kenwood forums?

 

i dont recall there is a setting in there to block this. perhaps unpair the device from your HU and then re-pair. see if you see some permission about the address book. there may be some low level setting on the EVO but i have not heard of this issue happening like you have. if no one has had this happen perhaps its something specific to your setup.

are you rooted? any software mods? any ROMs you are using?

 

in my vehicle, it has BT standard so when i paired my evo (and my hero and TP2 prior) it never once asked to grab my address book. i went into the BT of the HU and initiated that request.

why not let it add your address book? just leave it be for a minute until it syncs it.. then you should be golden yeah?
