Grown up here but this area gets the most reads. I have used a Medtronic pump and CGMS for ever. Was planning on switching to the T Slim and Dexcom system in the next few months, however in reading some of the fine print I am wondering if I will be able to update to the modified AP system that Tandem is working on for the low suspend option and maybe an even more integrated AP system in the next few years.Th e fine print says I have free upgrades through 2018 but then what?? Does anyone know if they will just charge for new software upgrades or if a more comprehensive AP system will involve getting a new pump? I will contact tomorrow to ask directly but if anyone already knows the answer please chime in.
