Hi
@crashbabacue

A Drum-roll Soft Start can help.... Hold the ON/OFF Power button in until you hear a Drum-roll sound... Then release the button.... This will reinitialize the devices Operating System, like restarting your PC

Fully charge the Battery (At least 2 Hours)
A low battery can cause GPS Satellite fix problems
First Plan a route on the device... Now place the device outside with a clear view to the sky
(I used a a 5200 mAh battery power-pack... while waiting for a Satellite lock)
It can take anything up to 30 Minutes to get the first Satellite Lock
After the Initial 'First Lock' the device should lock quickly onto the Satellites

HI @crashbabacue

Try this

Charge your unit for 2 hours and then take it outside well away from buildings and trees etc with a clear view of the sky.

Turn the unit on and when working do a Soft Reset ie hold the ON/OFF button down until you hear the drumroll sound then let the button go.

When it has started again create a route on it and when you would normally be ready to drive off leave it where it is and don't move it for as much aa 30 minutes plus t see if it locks on to the Sats.

It has been found that sitting it on a car roof can speed the result but make sure you do not leave it unattended. If you can provide a power source whilst it was searching then that could be beneficial.

All the best.

Hi
@crashbabacue

If your still struggling to get a GPS Fix
Try....
I have found with my Car parked on the drive, if I placed the device on the centre of the Cars roof (I used one of those 'Sticky' rubber mats to stop it sliding off the roof)
The device will obtain it's first GPS Satellite lock more quickly... The metal roof of the Car acts as a ground-plane for the SatNav GPS Antenna and increases the signal strength

Test... GO 825 Live connected to a 5200 mAh battery power-pack... PND Displaying 'GPS Status Menu'
(1)... Centre of Car roof (Parked on drive).....
Signal strength 86% Connected Satellites 9
(2)... Outside clear view to the sky.....
Signal strength 61% Connected Satellites 6
(3)... Indoors 1st floor one metre from window.....
Signal strength 51% Connected Satellites 4
(4)... Indoors ground floor one metre from window.....
Signal strength 41% Connected Satellites 3

DON'T FORGET... If your using the cars roof
Keep an eye on the device, you wouldn't want a family member driving off not knowing its on the roof or a Thief walking off with your SatNav

Also its a long drop from the Cars roof onto the hard surface of the drive, I doubt a SatNav would survive a fall like that

Use the above information at your own risk, the usual exclaimers apply

Well useful for a satnav in a city then..

Hi @APFF

Don’t knock something that has been seen to work. If a GPS unit has lost the ability to lock onto the Sats then taking it to somewhere that gives it the best chance to re-establish contact is the thing to do. Once it has Re locked on then in future it will usually find them quicker and in the more challenging environments as it is designed to do.
