My garmin quest is not picking up a signal I have tried removing the antenna and cleaning the socket and plug with contact cleaner, this only gave a temporray result and now it picks up only now and again. any ideas ?
Hello, I currently own a Garmin quest myself, and some time ago I had some strange problems myself, I am a electronics technician, and I do have a work around for you. I will explain the problems and a cure for you to try, none of the work arounds depend on any parts to be removed.
1. NO RECEIVING SATELLITE TELEMETRY. I beleieve this could be due to a number of reasons, but more so at sometime corrupted telemetry was the problem to fix this,
a turn GPS on
b. depress menu
select Time Setup
when in Time Setup depress MENU
Select SET DATE
Depress OK button
Depress OK button again on the numberic keypad that appears on the screen (DONE)
what this seems to do is resets the internal date/time clock and the unit starts to work again.
the Second workaround is this but takes hours to perform.
Simply turn the Guest on and allow the battery to fully discharge, usually this works to TOTALLY flush the Memory again, but on my unit I have to setup all the maps again, this is easy to perform, but just takes time. I hope this helps you.

Most likely a defective antenna connection. Two ways to fix this. (1) obtain an external "puck" type antenna with an SMA connector and plug it into the back of the Quest. (2) If you feel comfortable soldering small circuit pieces, remove the flip up antenna by placing the quest face down on a table. Remove the right two screws from the back and carefully remove the end cap holding the flip up antenna in place. Be careful removing the antenna endcap because there is a small plastic piece and a spring that can easily fly out and get lost. Gently pull the antenna to the right, away from the GPS, removing it completely. Take a small flat blade jewelers screwdriver, pry the pieces of the antenna shell apart exposing the antenna circuit board. There is a small gold colored antenna connector on the left side of the circuit board. Very lightly apply a very small amount of heat to the solder connections. Just barely enough to melt the solder. Reassemble the antenna and then the antenna to the Quest, making certain to include the small plastic piece and spring and then tighten the endcap and screws in place.
I have repaired quite a few Quest units with this procedure and have had only 1 that did not work afterwards and that was because the antenna itself was bad.
The best thing I can recommend is shop around on Ebay and hopefully find a basketcase Quest or Quest 2 with the antenna intact. Swapping the antennas is fairly easy. Lay the GPS display side down and remove the two endcap screws on the right side. Pull the old antenna out and to the right and replace it with the replacement antenna. Another option you may try is purchasing an external patch type antenna that can mount remotely and plugs into the back of your Quest GPS. Garmin WILL NOT sell you a replacement antenna. They want you to send it to them for repair and will charge you $100+.
You will need a small phillips head screwdriver. Turn the GPS unit over on its face with the back and flip up antenna facing you. There are 6 screws on the back holding the two halves of the GPS together. With the Quest oriented so the hinge of the antenna is away from you, carefully remove the two phillips screws on the right hand side of the back of the unit. This holds an endcap of the unit and the flip up antenna in place. Be VERY careful in removing this, as the antenna has a small spring putting tension on it and this spring will easily pop out and get lost. The antenna should easily come out at this point. If you look carefully, on the left side of the antenna, you will see the swivel for the connection. There is a spray called DeOxit used by radio repair people that does an excellent job of cleaning contacts. If that is not available, use a Q-tip and some isopropyl alcohol and gently clean the contact areas of the antenna and where it plugs in on the chassis. Allow the alcohol to dry or gently blow it out with air. Reassemble, (don't forget the spring), and it should work just fine.
Did you purchase this unit new? If not, someone may have taken the unit apart and lost a small spring out of the antenna assembly. If you place the unit, display side down, with the antenna hinge away from you, there are two small phillips head screws on the right side. If you remove these screws, a small plastic endcap for the antenna assembly will come loose and the antenna can be removed. Where the endcap and the antenna are hinged together, there should be a small spring that puts tension on the antenna. If the spring is missing, the antenna will not remain in position.
Do you have a heat reflecting windscreen? These are a total barrier to GPS signals. It may be getting the odd satellite through the side windows if you have such a windscreen. An external antenna, such as the ones supplied by Gilsson.co, would be ideal but you need to have an external antenna socket on the GPS. Not many car units have this feature. Another option is to try a re-radiating antenna but I've not seen these for ages - bought my last ones from www.rnrplace.com
This could get a little dicey, especially if you are not comfortable working around electronics. First try a "Master Reset". This is done by turning the unit off, then pushing the "OK" + "Page" + "On" buttons at the same time. If this does not fix it, then you may need to take the cover off the unit. This is where if you are not comfortable around electronic circuit boards, etc, I would suggest sending it back to Garmin. There are six small phillips head screws on the back side of the unit. With a small screwdriver, remove the screws. Be VERY careful with the screws on the right side of the unit (unit facing down with antenna hinge away from you). This hold the endcap to the antenna which is spring loaded. If you take the endcap off, you need to be careful with the spring that can pop out and easily become lost. Once the back is loose, gently pry the two halves apart. There is a small plastic plug with a red and black wire in a socket on the back of the circuit board. GENTLY use a small screwdriver or something similar and remove the plug from the socket. Leave it out for a short period of time (30-60 seconds), then plug it back in. Reassemble the GPS making certain the rubber gasket between the two sections is not crimped or kinked. Gradually tighten all of the phillips head screws in a criss-cross pattern until all are snug. Turn the GPS on as usual. If it is still locked up and the reset routine I described above does not work, it will most likely need to be repaired by the factory.
I got the exact same problem and I solved it. The problem was a bad contact between the flipping antenna and the unit.
On the back of the unit, removed the two screws on the right side, beside the flipping antenna.
Take care there is a spring that can fly away.
Remove the part that was holded by the screws.
Removed the flipping antenna (pull on right slowly).
On the antenna connector on the unit, there is a ring. That ring was loose.
Put every thing back.
The antenna is on a spring loaded hinge and over time can get dirty where it connects to the gps. I have seen instances where cleaning the contacts helped the performance. Just be careful when removing the plastic endcap on the back of the GPS. There is a small spring that can fly out of there and is lost easily.
