Has anyone had this installed on their 2003 and up S type? If so, how much did it cost and what system did you go with?

 

I noticed you found George's post about his dysfunctional FOB. Here are a couple you may find interesting:

Be mindful that George hasn't registered any activity on the forum since early Nov, 2015, but he does invite email at an address on his profile. You could try that. Bear in mind, he is an electrical engineer, audiophile, and car-dealer as well as avid DIY'er. Wonderful fellow and a great help if you manage to get ahold of him. Not trying to wet on your charcoal, just beware that just 'cuz George made something work, doesn't guarantee any average bear with a vise-grips and roll of duct tape will have the same success.
