It should not have been that painful. Having a mopar account already most likely wasn't the issue. you can add/delete vehicles to your "garage" as you please in your account.
But in my experience, if everything isn't added/verified/authenticated in a certain order, it does tend to mess up things.
I already had a mopar account setup, vehicle added, pin # created, but it appears that data from Sirius Guardian does not always sync with mopar.com the way it should. There are some complaints about this for alot of 18 year models as well.. Also, a software update cause all my information to be lost, so i had to re register. Everything to sync back in 2 days.
I highly doubt I will pay for sirius guardian after my trial expires. I might consider the hotspot.
I had the worst time getting it set up because for some reason i had a Mopar.com login for my ‘12 wrangler. Getting everything switched over to the ram and getting to set up a pin required talking to 3 different departments and ultimately having my Mopar account set up to a new email address. Best advice i have besides that is that change to the account, etc seem to take 24 hours+, so wait for “welcome” emails.
Now that i have it, it works. Remote starting takes up to a minute. I plan to use it in the very cold /snowy days of winter from inside the office when key fob is out of range. Otherwise i can’t imagine using it. We’ll see if it turns out worth paying for after that ...
