I bought a AutoCommand remotestart unit from H2Source and Im about to get my mechanic to fit it - Im in the UK so hes not done one before although he works on US cars.
I got a couple questions...
How long should a normal install take?
Can it go seriously tits up considering its messing with alarms and what not?
How is it once installed...anything majorly bad (or good) I should be aware of?
I should of asked these questions before I bought it!

Im ready to suck up the advice...
