Frequent Lost Satellite Signal on 3560LM

[carlover]

Anyone using 3560LM here?

Recently I have issue with my 3560LM as it keep drop signal frequently even on clear sky on the empressway.

I notice there are times that it does not pick up any signals at all when there is no signal indications on the signal page. I dun have such issues previously and it is coming to a year and the warranty will be expired soon.

I have sent it back to Garmin thru AllBright, their boss also tested it with me on a short testing route and deduced that it is problem with my car.

I have also install the Re-radiating antenna but it does not solved my problem as when I park a place with no blockage, it will also drop signals.

I really give up on this set and thinking to change to another GPS, anyone has any advice?

Hv you tested it in another car without any tint ?

Are you sure the re-rad antenna is boosting the signal inside your car ?

Brother, I only got one car so no chance to test on another car.

How to test whether the re-radiating antenna is working?

Bro I am sure you have buddies who drives and your Nuvi is portable

Unless you have access to signal strength meter, you use what you have. Put re-rad external antenna outside your home. Put the re-rad internal antenna inside your homw as far away from windows. Put you GPS next to it. Does the signal strength improve ?

Brother, thanks for your suggestion. I have already install the Re-radiating antenna on my car so dun want the hassle to remove and install back again.

What I have done is borrow another set of gps then on the same spot, put one set of gps outside the car like on the bonnet, the other set is mounted inside the car with the re-radiating antenna power on and see the Satellite signals on both gps.

Then power off the re-radiating antenna and compare the signals again to test what is the issue whether it lies on any interruption inside the car or gps issue.

I guess it should be OK to test like that, right? Or you can assist me by testing it in your car?

No need to remove rerad antenna installation. Just unplug power to rerad and note accuracy then replug and note if any change in accuracy to tell if rerad is working.

If no signal detected, remove your Nuvi and move it to the bonnet and check the accuracy again. If still no signal outside car and you have clear view of the sky, then maybe your Nuvi is the problem. If there is signal outside car but no signal inside car then problem may be tint film.

Where is your external antenna for the rerad located? It should be outside the car and more than 1m from your Nuvi location.

Your way may not be conclusive if the one on the bonnet is already at max accuracy.

Try out what Bro JasonLee suggest.

If you want to we can arrange one Sunday afternoon to test it out if you want to.

I have both an ICE Garmin GPS installed in my car and a Nuvi 3790 / 1350 though I use only one of the three.

If I remember it correctly you live in TP ?

Brother, thanks for your offer to help out.

I managed to solve my problem after doing a trace on what cause the interference in the GPS Signal near my car dashboard area.

I have the default In-Car GPS installed and the antenna is installed on my dashboard, it do looks like the external antenna which is square in shape.

When I plug out the cable for that antenna, the GPS signals came back in full signals then once I plug it in, the signals all went off.

Conclusion, that antenna on my dashboard is faulty so causing interference near my dashboard area. What I will do is to plug out the cable as the GPS map is not updated and I seldom use it too.

I also decided to sell off the Re-radiating antenna, let me know if anyone interested.

Great news that you solved the problem.
