I have updated it with Sentinel, I live in Grapevine, I cant hear anything from Tarrant county. Dallas county I can hear plenty. I have set my range any where from 20 miles to 1 mile with no change. I have entered my zip code 20 times.
Are you using a Favorites list, or scanning using your location and range and the main database.
You updated the main database in Sentinel, then chose 'write to scanner' to get it updated in the radio? Database in Sentinel should be dated 01/29/2017. On your 536, try this:
Press the Menu key
Scroll down to Manage Full Database, and press 'E' (Enter)
Now, scroll to 'Information' and press E again. What version of the database does it show? What date.
In setting your location, are you doing that in Sentinel
as well as on the scanner itself?
When I visit a friend in Grapevine, I can hear the NETCO layer (which includes Grapevine, Southlake, Bedford, & the others) with no problem.
