Based on the
database for AWIN here on RadioReference, you'll need to program your local site(s) for the system and then the talkgroups for Troop I (1601, 1602, 1603, 1604, 1605, 1607, 1608, 1609, 1611, and 1613). Don't leave a wildcard programmed in or you'll receive any talkgroup that affiliates with the local site(s) you are scanning.
It's been a long time since I had or programmed a 106 so maybe someone else that knows more first-hand will jump in and provide additional tips.
