Yeah I'm pretty sure I'm getting interference from somewhere. My Garmin didn't have a satellite lock the GPS data app on my cell phone was showing all the US Satellites with real low signal but was picking up glonass just fine, and my Qualcomm is only showing 4 out of 10 satellites.
Not sure what it really could be because I haven't added any new electronic devices to the truck or anything... It's also not a constant thing as yesterday I had GPS signal full all day long just about. Now for the last 6 hours I've had GPS for probably 1 hour and the last 5 hours everything's been searching.
