I had several imi-1000 units from the guys at integrated automotive. They’re Leicester based and do their own tests and development etc. I installed mine myself, it’s fairly easy to do but you’ll need a good few hours and a lot of patience.
If you’re like me and get aggravated by holding your breath while concentrating, which makes you angry and heavy handed, then you’ll want about four hours so you can walk off now and then and come back calm with softer hands and no blue language after a cuppa’!! It’s a really simple job to do nice and tidily, but take your time.
Scott at Integrated Automotive was always on hand with guidance for when you get stuck or need a confidence boost for the next few panel clips you’re frightened of breaking because they’re holding on like a so and so!
Failing that comandonline will fit the imi-1000 and do all the swearing for you. Have also used those guys and they’re slick as hell at getting on with it all.
