Remote Start works in town but not at the house. I'm guessing that this is because Volvos use a cellular modem (sim card -probably AT&T) and signal reception is poor or non-existent. Verizon is the only cell that works consistently at the house, which is only 7 miles south of town. Basic security features such as locking are also activated by the key fob but convenience items are only on the app. So any brand or model that has a modem and features that require an app may have connection issues.
(I think I can connect the Volvo as a device to the house's modem.)
So if you have your heart set on firing up heated seats from your cabin in Wyoming, you may want to check it out beforehand.
