This thread escalated quickly hahaha.
When I look at these mfr things, whether it's Polestar Tune, or the Volvo app subscription... I always remember their game is pricing by "value" what will people pay. Everything that do is playing that game, packaging options, accessories, everything. If there are enough takers then the price is good for them. Everybody wants to get in to what the little pieces cost and stuff, that matters to what value you think you get, but it's not the basis of pricing. Now I do think the app is a little lacking, they could add adjusting the climate temp, or turn on the heated seats (my daughter would like if I could turn on the rear one when remote start ;-).
The 4 years free is a good move though, it takes away the complaints at purchase and is satisfying when others complain about buying the BMW service and your Volvo just comes with it. Looks like they want to re-coup some of those dev costs after the 4 years runs up though (not that everything isn't costed into the MSRP)
The OEM has and wants to maintain "integration" that's their trump card. It's easy, it's already there, it works smoothly in the car. It's hard for aftermarket/outsiders to develop that.
Though there is MidCity start thingy for the fob start if that's all you want. And I have tested VDdash VDD device it can do some more things than the Volvo app, covers your remote start (with a slight bit of additonal wiring needed and takes up the OBD port.) I haven't priced it out, it needs cell service too. It's pretty good though, they are clearly offering another option.
