Area code 49001 needs to have channels added. Antenna picks up more than Tablo has listed. For example channels 52,35, 5, 43
The zipcode does not limit the channels which show up in a channel scan.
Did you perform a scan and not see those channels?
Or do you just mean the guide info is missing from the live TV grid?
If guide is missing those channels from the grid, try changing the Zip code to another one nearby.
Also you can watch with no guide data by pressing play.
