iWindows by TVonNAV iWindows in Action!
For our USspec E46 3 series, it is not possible to raise the windows with the remote key. One may think this is very odd since lowering the windows with the remote key is possible. In Europe, E46 have the option to raise the windows with the remote key. To my knowledge, it is a safety issue for US cars.
But TVonNAV is here to help. They have created a little unit called iWindows. iWindows allows you to raise or lower your windows with your remote key! Additionally, it allows one touch feature; this means you do not need to 'hold down' the button for it to lower, you can just tap it and it will go down automatically.
If you want even more, they offer iRain. This unit in conjunction with iWindows, raises the windows when it senses rain.
After using it for a week, it has been great. One fault it has (which TVonNAV have already addressed before I purchased the unit) was on coupes, whenever you use iWindows to raise the windows, the windows will not go back up for that 1/4" window tuck when you enter the car the next time and close the door. You must manually use the window button to raise it. Yes its a bummer but IMO raising the windows with the remote is very useful to me. On sedans, I believe there are no faults.
