Thanks for your posts. I have CarlinKit t2C for Tesla and find that it disconnects quite often and sometimes is a pain to connect too. Also - I have not received a firmware update in a while, so not sure how it is being supported. Will the new “Tesla Android Project” premade systems be better and more reliable? Do you have to use a SIM card for those. Really want the easiest, best possible experience and best quality. The premade ones are a lot more expensive than CarlinKit t2C, so guessing there is some positive reason why? Thanks!
