The L322 owners manual ( 2002) , warns you not to use a phone with a built in aerial, inside of the vehicle, as this may cause electrical problems. I asked my Indie, who was workshop manager for Land Rover in Portugal, and had visited the factory for training when the 2002model arrived, if this was true, and he said he'd experienced one case like this, where the factory stated that the electrical problems were due to protracted cellular phone usage whilst inside the vehicle, with motor running. I had a passenger once who after a long conversation, I imagined that my airco was not operating correctly. However it rectified itself after a long interval parked and then turned on ignition again.
Is it possible, that many of the electrical niggles that crop up are in fact due to protracted use of cell phones by passengers ?
I now tell my passengers to turn off their cellphones if they expect many long calls.I use the original cell phone in the satnav system, and not my normal cellphone. Range Rover Vogue TD6 2002

Can't see it to be honest. I do remember stories of airbags going off and mobiles being blamed.
If you are asking passengers of switch off their mobiles, you should put life jackets under the seats and remember to show them the exits as well.. Just to be sure.  Previously..

If I'd still be living in Amsterdam, I would certainly take your advice on life jackets under the seats etc, BUT a far better course of action would be to enrolled them into one of the MANY courses, on how to escape from a car, sinking under water in a canal or lake.Much more practical? Range Rover Vogue TD6 2002

So do you switch off your mobile in petrol stations too

It 's ALREADY off as I 'm driving the FFRR. Do you? If in the defender it 's off too- I don't want to talk and drive,especially when practicing my defensive driving here, trying to stay alive a little longer.Many twists and turns here where I drive, and usually short trips- nothing urgent that requires cell-phone on in the vehicle. A friend of mine was recently "caught"on the motorway using her cellphone, luckily she was in a British registered vehicle, which was right hand drive! Rather embarrassing for the cops on realising their mistake. Range Rover Vogue TD6 2002

Phone always on and I'll use the Bluetooth, so I don't need to touch the phone

I think the manual says don't use a phone with it's own built in aerial. When using Bluetooth, is the phones aerial by-passed?I'm not into electronics so could someone give a simple explanation of how Bluetooth works as opposed to a cellular phone not on Bluetooth but with an built in antenna of it's own.?
Thanks. Range Rover Vogue TD6 2002
