Read the xcusion manual on the Bluetooth. I had the same phone (broke right now)and would connect to the Tungsen2 via buletooth. The actual phone dailing from kx160b through T2 would not work, but could push vCard. The T5 may need an update to its phone database? Hope this helps some. You just have to play around with the BT.
