Looking for advice on remote start options for 2016.5 GT. Since a 2nd key fob is required with the OEM implementation, I'm also considering aftermarket options (from a reputable installer - not big box stores). I have done a bunch of internet searches on this, but there is not as a lot of information specific to the 2016/2016.5 models and I am not sure if anything changed.
1) any options that get around the engine off when door is opened? i don't think so but figured i would ask
2) any controls over heat, defroster, etc...? Does it remember the last setting and continue or is it just start or stop?
3) will the keyless entry still work (ie; the little button on the drivers door that unlocks the car. Not eh OEM fob button)
4) does the phone enabled module / app provide additional functionality like control over heat, defrost, heated seats, etc....? Wifey needs to start it from her train, and the phone app provide that distance capability. Not the MMS module/controller, but an aftermarket version. I actually spoke to my local mazda dealer today and they flat out told me that they wouldn't install the MMS system because there are lots of issues Mazda is trying to work out. I am sure they will fix those issues, so that is still an option.

Aftermaket is much more affordable. I can get the Prestige single button remote start (APS901E) for $350 installed. Viper and others manufactures, let me know your thoughts. Happy Mazda owner and thanks in advance
