After having my S5 stolen 5 weeks ago I’m looking at getting a tracker and immobiliser fitted to the new one I’m picking up tomorrow. Audi have recommended the Vodafone Protect & Connect 5. I just wondered how big the cards are and how you carry them around. Are they like credit card size that you can put in your wallet or are they like a key fob with a hole that you can attach to a set of keys. Otherwise I’m just conscious that it’s another thing to forget when leaving the house.
