Question about GPS

My internal (folding) antenna has broken as the GPS fell down while driving the car. Even the wire connections are broken. Is there any way I can solder new wires and be able to attach the external antenna?

Most times this is very fine detailed work and should not be attempted by the unskilled.
You need a very fine needle point solder tip and even then you can get heat transfer to the board tha can do more damage.

2 options bin it or take it to the manufacturers repair agent But expect to pay big bucks for repair.

My Garnin 660 can't receive any satellites with its own antenna, even if I am out in an open area As soon as connect Garmins (GA25) extra antenna it works fine. Can anythig be done?


Hi
it could be the internal antenna is broken.
Have you tried installing all the firmware updates on the device from the gamin website.
They have done quite a few and it is possible one could improve sensitivity.

I have a Garmin 3600. When I want to use the GPS feature, and I open the antenna, all I get is Acquiring Satellites, but nothing happens (the little indicatior on the bottom shows activity). I thinkthere...


If you can obtain an external antenna from another IQ3600 user it
will plug into the connecter on the top of the unit and bypass the fold out antenna. I had to buy one because the windshield in my Pont Montanna would block the satalite signals. When I plug in the external antenna I do not have to fold out the antenna on the unit.
That will check to see if the unit is recieving and /or if the fold out
wire is broken. The external antenna is not Garmin specific but the
plug on the end is so another gps antenna with the same end plug works.

The GPSmap 60CSx will not acquire a satellite signal even in open water with clear skies on Lake Michigan.


I suggest trying a external antenna. This will let you know if the internal antenna connector is broken. You can also do a system reset. Back up all user data first then;

Power the unit on while holding down the Page and Enter buttons. Hold them down until you get a prompt that asks you if you want to RESET. Select yes and lets hope that works. Also doing a update may fix the unit also. To update just use the free program WebUpdater found on Garmins website. For assistance please feel free to contact GPSCity the gps experts

My antenna no longer seems to work, is it an easy fix?


The antenna connection on the Quest is very fragile and is easily broken internally. Fit an external antenna and this should fix your problem.

Get it repaired at Westek


This problem is not caused by poor solder joints. It's caused by a defective part. We sent a "marked" defective unit to the repair shop mentioned above and upon its return, disamantled the GPS receiver assembly and made the following evaluation:

1. The shop did NOT replace the defective component causing the initial problem in the 1st place. The defective part was STILL in the circuit.

2. The shop placed a wire jumper between the internal antenna and the external antenna port. This type of modification places a +2.5VDC bias on the internal antenna and essentially shorts the internal antenna to the external antenna (when connected), giving unpredictable results. It also affects the circuit impedance and signal strength. This is not the correct way to resolve this issue.

3. The defective part needs to be replaced with a higher rated part. This type of repair returns the unit to full functionality and allows the unit to properly switch between the internal and external antenna as it was intended to do by design

Can't find satellites


The internal antenna BNC connection (the little steel bayonet that the secures the antenna or extender cable) is a common failure on these units. The threaded retaining ring on the outside of the antenna BNC comes loose when installing/removing the antenna connection, and eventually the BNC rotates and the solder joint inside fails. This happened on mine recently, if you are handy fixing small mechanical parts and a good solderer it is pretty  easy to fix. Remove the batteries, remove all six outer case screws (but not the one with the oval metal plate) and gently pull the housing apart. Check the solder connection of the coax wire to the BNC pin & shield. If it's broken and the BNC is loose in the GPS case, tighten the outer BNC retaining ring VERY tight, add a drop of thin super glue (Hot Stuff or Permabond CyA, etc) to keep the ring/BNC/case mated, then repair the coax solder  connection. Replace all the screws and test it outside. If it's an aviation GPS you would of course have this done by an FAA licensed avionics specialist. Wink wink.

you should see it now
There is a known hardware bug in the Garmin 600 series relating to the detection of the connection of an external antenna. The GPS is supposed to do this automatically and when it detects an external antenna plugged in it switches out the internal antenna. Unfortunately, this circuitry doesn't work correctly in some versions of the unit and sometimes it get's comfused and thinks there is an external antenna connected when there is not. This causes the behavior you describe because, for all practical purposes, there is no antenna connected.

Garmin can fix this and they've been known to fix it even on units that are out of warranty. There is a fix that can be done by someone with the right equipment and know-how which requires disassembling the unit and bypassing the antenna switch. Not to be attempted by anyone not experienced in micro surface mount PCB re-work.

Has this problem just devoloped, did it work before and it's now broken or have you just obtained this device or installed it into a new car.

your car might have athermic windscreen/heated windscreen. check the details of your car and see what UV protection your car has as often you will not get a signal through your windscreen if you have any special glass.

The solution to this would be an external antenna.

other wise how good are you at soldering. you might have a lose connection on the internal antenna. from all the bumping it does in your windows while driving it could have losened something inside.
