I need someone to point me to a video that shows you how to manually enter frequencies in the Sentinel software for Home Patrol 2. Not pulling from the database. Entering new frequencies and saving them via the Sentinel software as a favorites list. I have heard it can be done without the Extreme Upgrade but not sure. Also can anyone show me a legit place to get a Extreme Upgrade key to enter in the Hompatrol 2 to unlock it to enter new frequencies directly into the unit if indeed I need the Extreme Upgrade. The Uniden website gives me a error 404.
