I'm embarrassed by how long it took for me to get my SDS running. I did not want to even attempt the zip code feature and opted to program only Favorites. I wrote here about some of the issues; no picture of the unit pointing out all the connections, keys, definitions and more. It seems on one hand Uniden acts like the SDS and Sentinel are one entity (you need to use Sentinel to get things updated and going), but on the other hand doesn't explain clearly how to do things in each manner. One thing I wanted to do is edit the display. The documentation shows how to do this with scanner keys. But I wanted to edit in Sentinel, which is shown, but not clearly explained.
I've never liked the Uniden User Interface, although it has more capability than GRE's. The thing better in GRE is that everything is named with a user edited Text Tag, you don't get that with QK nor Departments/Sites in Uniden. The thing I like better in Uniden is how sites are handled for trunked systems. You can assign QKs and "easily" turn them on/off. In GRE you either lump them all together in one TSYS or duplicate TSYS objects (each with its sites).
As someone pointed out in another thread, this shows how much we all miss Paul (UPMAN).
