TT5 upgrade trying to phone out?

upgraded to tt5 from 2 (wish i hadnt)
Three problems keep geting warning window saying unable to connect or no network card installed despite having no isp set up etc cannot seem to stop this is tt5 trying to connect for these additional services like weather etc??

also street search is sluggish on tt2 was quicker probably because i only had se england loaded not whole of uk. is there any way of improving search speed? I only use the pda for satnav.

lastly on tt2 contacts navigated smoothly now tt5 says unable to read please check entries any ideas?

Many thanks in advance if all else fails how can i go back to tt2 and bin this upgrade?
