Using a GPS these days can feel like second nature. You just plug in your destination, and your phone or in-car navigation system tells you exactly how to get there. Most of the time it works flawlessly, but every now and then, your GPS can go haywire and leave you feeling lost. Don’t panic! With a few simple troubleshooting techniques, you can get your navigation system back on track.
From signal loss to freezing screens, GPS hiccups happen to all of us. But by understanding some of the common causes and solutions for GPS fails, you’ll be well equipped to handle any navigation emergency. Consider this your helpful guide for when technology throws you off course.
Can’t Connect? First Check Your Location
One of the most common problems with GPS is struggling to initially connect and acquire satellites. You fire up your navigation app, but it shows your location pinging all over the place, sometimes in totally wrong areas. Or it simply spins and spins, desperately searching for a signal lock.
Before assuming your GPS is broken, first check your surroundings. Are you indoors? In a parking garage? Under a bridge or in a tunnel? Being inside or around tall buildings and structures can severely hamper your GPS signal. These obstacles block and reflect the satellite signals, making it difficult for your device to pinpoint your precise location.
For the best chance at acquiring a signal, head outside to an open area away from buildings, trees, and overhangs. If you’re inside a building, move closer to windows so your device has a clearer “view” of the sky. High up locations are ideal, so the upper floors of a hotel or office building may connect better.
I’ll never forget the time my old Garmin GPS stranded me in an underground parking garage in Los Angeles. Once I drove up and outside, it snapped right to my position. So remember, clear skies equal clear signals.
Update Software and Map Data
Another common source of GPS headaches is out-of-date software and maps. Navigation apps and hardware are constantly improved, with new software versions released periodically. Outdated software can definitely cause glitches and connection problems.
Check your device settings and app store to see if any software updates are available. Installing the latest version gets you the newest features and bug fixes. For portable navigation devices and in-dash car systems, you may need to connect to your home computer to install updates.
Along with software, verify your maps are up to date too. Maps add new roads and points of interest all the time. Using outdated maps will leave your GPS clueless when you drive through a new subdivision or visit a recently opened store.
Most navigation apps offer regional map downloads or subscriptions to stay current. Occasionally re-downloading updated map data keeps things fresh. Don’t forget to update maps on your smartphone and in-car system too.
Reset and Restart Your Device
Like any gadget, sometimes your GPS just needs a good old fashioned restart. Over time, navigation devices can get bogged down, with processes freezing up in the background. Resetting your GPS clears out any glitches gumming up the works.
For smartphone apps, rebooting your phone completely will do the trick. Just power down your phone, wait 30 seconds, and power back up. Give your navigation app a fresh launch to see if things improved.
For dedicated GPS units, a master reset restores factory settings, which may resolve pesky software issues. Just be sure to back up any favorites or saved addresses first! Consult your owner’s manual for device-specific reset instructions. Generally it involves holding power + another button for 10 seconds until the device reboots.
In a pinch, removing the batteries counts as a reset too on some models. And remember to restart your in-dash navigation system by turning your car off and on again. Amazing how a simple reset solves the quirkiest tech behavior!
Verify Sensor and Antenna Connections
Under the hood, your GPS utilizes an antenna to receive satellite signals. On smartphones this antenna lives inside the phone itself. For portable navigation devices and in-car systems, it’s typically an external antenna.
Over time, antenna connections can work loose from vibrations or damage. If your GPS is struggling to lock onto satellites, inspect the antenna to make sure it’s still securely connected.
Refer to your owner’s manual for antenna locations. They’re often attached to the rear or underside of the device. Check that connections are snapped in place and cables are fully plugged into ports.
I once opened my glovebox to find the antenna cable for my car’s GPS dangling free from vibrations. Plugging it back in restored the signal immediately. Don’t forget to inspect roof-mounted antennas too. Secure connections are key for reliable satellite locks.
Many GPS units also utilize motion sensors to track your heading and acceleration for dead-reckoning navigation in between position fixes. If readings from these sensors get screwy, it can throw off your location accuracy.
Reseating sensor connections or performing a master reset typically straightens out any sensor issues. Just like your antenna, ensure motion sensors inside your device remain securely anchored in place.
Eliminate Magnetic Interference
Magnets – they’re not just fun fridge decorations! But magnets ARE kryptonite for your GPS.
See, magnets emit invisible magnetic fields, which can disrupt and distort the sensitive electronics inside navigation devices. So keeping magnets far away eliminates interference that can play havoc with your GPS.
Smartphone cases with embedded magnets are a common culprit. Ditch the magnetic case and see if GPS reliability improves. The same goes for magnetic phone mounts. It’s best to separate magnets and your phone by at least 6 inches while using navigation apps.
Portable speakers, tablets, laptops and other electronics can also contain magnets that interfere with your GPS when nearby. Notice your location jumping around wildly after placing a phone or speaker atop your dash? Magnets are likely to blame.
In my car, my GPS refused to connect until I moved my magnetic air vent phone holder to the rear seats. Keeping magnets as far from your navigation device as possible really helps.
Leverage Other Location Services
When GPS satellites remain out of reach, don’t forget your device has other tricks up its sleeve for positional awareness.
Cell tower triangulation uses nearby cell towers to estimate your general location, though not as precise as GPS. WiFi positioning notes the nearby WiFi networks and compares them to a global database of WiFi hotspots with known locations.
In a pinch, these network-based methods provide enough location context to get you in the ballpark. Apps may show your location jumping between towers or estimated based on WiFi, but it beats flying completely blind!
Some navigation apps like Google and Apple Maps even crowd-source location data from other devices to aid navigation when GPS is unavailable. The more devices sharing data, the better the positioning from WiFi and cell towers.
So rest assured your navigation app has some GPS backups when satellite connections fail. The accuracy may suffer, but other location services can get you back on track in the meantime.
Identify Hardware Problems
When all else fails, hardware problems like an aging receiver chipset or weak antenna could be hampering your GPS connectivity. If you’ve tried every troubleshooting step with no improvement, hardware issues may be the culprit.
Compare your GPS behavior in different locations to help isolate problems. Does it struggle to lock on even when outdoors with a clear view of the sky? Do you see vastly improved signals and speed when using other people’s devices? This points to possible hardware flaws.
For older navigation units and vehicles, the GPS hardware may just be getting long in the tooth. Consumer-grade GPS chips tend to last 3-5 years before performance suffers. Reception issues that worsen over time indicate aging electronics.
Inspect your navigation device for any external damage too. Cracked screens or cases can allow moisture and debris inside to damage antenna connections. A visibly damaged or weathered antenna also implies hardware trouble.
If you suspect hardware issues, replacement may be your best bet for reliable GPS navigation again. Costly repairs often don’t make sense for aging consumer electronics. Just make sure to back up your data and settings before parting ways!
Stay Calm and Navigate On
If your navigation app starts glitching mid-trip, perhaps switch to old fashioned paper maps as a backup. Or try asking locals for directions – you’d be amazed how friendly strangers can be.
