Cell Phone Messing With Alarm

[janel34]

Lately, since I've switched to a next generation cell phone, and I've noticed that the cell phone seems to be interfereing with the alarm on my highlander. The highlander has the toyota alarm that features the in-cabin microphone (for glass-breakage detection). Anytime I leave the cell phone in the hl for an extended period of time (one hour or so), it sets off the alarm. Of course, my friendly local toyota service ppl couldn't find a thing wrong with the alarm. My husband and I think that when the cell phone is searching for a tower, that it causes the microphone to set the alarm off.

Just wanted to give you all heads up about this. Lesson: Don't leave your GSM phone in your highlander (if it has that alarm) or you'll have upset neighbors. It usually does this at 2am. :-)

I have that issue with the aftermarket alarm i have on my tundra for some reason or another if i leave my cell phone in the truck on vibe mode (during a call) in the center part of the tundra it set's my alarm on as well I have no clue why this is different than my last ericsson t60d but for some reason the new gsm uses new signal's strengt that seems to affect the alarm..weird....

Some older jetta's have a problem with 2 way radios on channel 6. If you turn one on next to one it kills the computer as ths signal interfears.

I know a lady with nextell that works at my school was having problems with her cellica stalling and not starting. Well she took it to the dealer and they never found the problem. She took toyota to court and lost as the car worked fine while in posession of toyota. Her phone was causing interfearence with the cars compouter. Its nothing new, these problems have been around since the 80's when computer management came about.

Mine does not set off the alarm but it sure screws up the radio when on or ringing in the Sequoia. It does not do this in the Avalon.
