I did get a quote from a meta dealer .. they wanted £325.00 for an upgrade alarm ... Thats the most expensive quote I have so far

yes mine was including fitting, I will let you know if its any good and which one they fit, as I am going to get it sorted this week.

Great - I would be interested to know

The Meta (Fiat fit) ones are excellent,never had a problem in years & fitted hundreds of them.Ultrasonics adjust themselves although you can override this & turn adjustment up/down but the setting they come from the factory with needs no adjustment 99% of time.
Labour prices to fit are bit higher as interfacing with the locking requires drivers door panel to be removed & wires passed through thus extra fitting time.I'd ask to speak to technician first to make sure he has already fitted one to a stilo as can be bit awkward & to ensure you get a good installation...the key to any good alarm system.

This is getting confusing - Can anyone recomend a good company with UK mobile fitting (Im about 25 miles from London).
