Cell Phones vs. RX65

So I got my RX65 back from GOL, and I installed it in my GF's car since I run the X50 in mine.

I remember getting a Laser false every once in a while from using my Cell Phone close to the RX65, but it only did that at night. I have a Samsung phone and AT&T/Cingular.

Now that it is in my GF's car, she gets laser falses a lot whenever she is on her Cell Phone, and it happens day or night and a lot more frequent. She has a Nokia phone and T-Mobile.

Did we ever figure out if the falsing was caused by certain phones or by certain Providers?

Does anyone with the M4 RX65 experience this issue?

mine doesnt do that i have cingular and its a ericson phone the only time i get lazer falses is when i go through a tollbooth mines the m4 2.9

mine does it on KU somtimes and all the time on Ka with my mates samsung

I got laser on my PNI Silver Bullet if I hold it right under the detector with a call in progress. My provider is Rogers, using GSM technology.

Could it be falsing on the screen the same way that some detectors false when they see a nav display?

My RX65 (v4.5) falses on my Motorola V3 on Fido. I must use a bluetooth headset and hide my V3 in my pocket to avoid laser falsing while talking on the phone.
