2010 tl cannot import phonebook. I tried it one time and it worked. After deleting it accidentally, it won't re-load. Also, i can't seem to load phone numbers individually. Anyone have any advice?

 

If my memory is correct, the ability to download your phones phonebook into the TL's memory depends on the phone type/style. Since you indicated it was loaded initially, it should still load properly. And you cannot load individual phone numbers to the memory - you will need to reload the entire phonebook if you add/delete a number from your phone.
