It says in the manual that there is place for 400 contacts.

 

I have 261 and when the transfer completed, the last 51 didn't transfer.

 

Any idea why?

 

It wasn't random 51 so there is not a problem with this numbers but the last 51....

From the manual:

 

The maximum 400 entries can be transferred

per cellular phone. If the entries exceed

400, the extra entries will not be

transferred. If more than one number is registered

for one person, such as work place

and home, each number is counted separately

 

 

I suspect your question is answered in the third sentence.

i got it working. it was my mistake, i canceled the download accidently so the avic didn't download all of the contacts.

 

works great now with the 1.9 update
