Car Charger = Crazy GPS?

[Mucuna]

Hi there.

I got a phone car holder and a car charger to properly use the GPS function (I use i-Go Amigo).

The problem is that the GPS is going a little crazy. It losts its signal, "spins my car" (the arrow in the screen stars to spin), transport me to another (wrong) place in the map, etc.

It doesn't happen all the time and it is usable, but very annoying.

This kind of stuff did not occur when I was using GPS just on the battery (for testing). I can only imagine that the car charger (not original) is interfering someway with the GPS software/signal.

Is it possible? Must I consider buy a original charger or there is no possibility that the charger is doing that?

Thanks!

PS.: Oh, I also use QuickGPS to get signal faster.

Is the charger built into the holder? If so that might interfere with the signal. Otherwise it is more likely to be the holder than the charger causing problems

Really? Never imagened!

But no, the charger is not built into the holder:

How can the holder interfere in the GPS signal? Is it because it may be obstructioning the antenna spot?

Gonna test with the charger but without the holder and see how it behaves.
