I have a louder siren fitted and it beats the OEM sound of a microwave. Damn those Germans for having laws/regulations against loud sirens!
Also have the glass break and it's quite clever. A guy outside dropped some glass and it differeniated and did not sound the alarm. Even in the rain it has been good. It picks up silent glass break too which is what thieves are now doing.
As for your car being safe after 03/2007 that is the biggest load of codswollop they are feeding customers. They tried to feed me that bullshit as my car is 01/2007. At the end of the day if you have an electronic key you are at risk! Fact.
I had a massive argument with Cooper Reading about this as they left me vulnerable telling me that I did not require the update.
