Today I was driving and thought I got my first radar alert with it. I was on the freeway and threw my cell phone onto my dash a couple inches away from the 9500ix which is currently mounted low on the windshield about 3" above the dash. Within a few seconds the laser alert went off. I thought it was odd because I was in heavy traffic that was moving about 5 mph below the PSL. The alarm was going off for an extended period of time so I put 2 + 2 together and figured it was the cell phone. I moved the phone and the alarm stopped. Put the phone near the RD and laser alarm goes off virtually every time. The phone I was using was a Blackberry 8120. I put my other cell phone next to the RD and nothing happened.
The moral of this story is not to put a cell phone near your 9500ix. Apparently they are sensitive to interference from the phone. I would be more concerned that the opposite may happen and the cell phone may prevent the RD from going off if the phone were left near the RD. No way to really test that but I don't want to find out. So I will no longer place either of my cell phones on the dash close to the RD.
