OEM Sirius install

[KevinC]

While wasting time tonight, I happened upon an E46 Sirius module install video on YouTube. The E46 head unit is essentially the same as our E85/6 head unit with slightly different cosmetics. I was pleasantly surprised at how navigating between stations works, and what info is displayed - on the tiny non-nav display I always assumed this was a royal PITA and therefore was of no interest to me.

But now I live in the middle of nowhere, with literally ZERO FM stations within range that I want to listen to. Now I want to add OEM Sirius. I found this unit, which appears to be the current/final one that's the correct fitment for our cars, and at $300, the cost is reasonable - especially if it includes a 1-year subscription (does anyone know if it does?):

Questions:

1. What other parts are required? What's a fairly simple antenna solution, perhaps something I can mount under the rear window someplace?

2. Is any subscription included with this unit?

3. Has anyone installed this thing and have any comments?

I've searched around and most of the Sirius info for the Z4 (here and everywhere else) is ancient and not of much help. Thanks for any insight anyone can provide.

How’s your cell reception? I just use the app and stream via aux...

Spotty. I'm really in the sticks. Otherwise it's a pretty good solution, though I really want the integrated experience.

Do you have the link to the YouTube video? Wonder if would work on mine also? I have an 03 with the business CD head unit.

Unlikely that it would include a subscription if it's through ECS.
I have a less elegant but more versatile solution.
Radio from Sirius in a vent-clip dock plugged into the aux.
Pop the radio out when I get home and dock it in the house with an FM modulator.
Listen on any FM radio in the house.
Car and home on one subscription.

My girl has the full-zoot subscription (including streaming) so I can already stream anywhere in the house, including on Alexa devices, as well as on my phone if I want to go that route and use the aux port in the car. But I hate fumbling around like that. It's OK on a long road trip, but for day-to-day use, it's too fidgety for me. I want the integrated experience. There is surprisingly little info out on the web about E86/E86 installation. There's an install kit (bracket and such) still available for the vert, but I don't see one for the coupe listed anywhere. I'm sure I could stash the little box securely without much trouble, but I would really like to confirm functionality with the ECS $300 box before spending a bunch of cash. Also not sure what the best antenna option would be. I want to keep it inside the car, under the rear hatch glass someplace if practical.
