Why I made this guide

I leave a printed copy of this guide with every customer after I install or troubleshoot android auto setup. It lives on a kitchen shelf next to the appliance manuals so they can reach for it the next time something acts up — or the next time a neighbor asks "is it worth it?"

No ads. No affiliate links. No fluff. Just what I'd want my own mother to know.

Need help with this?

Reading is one thing. Doing it is another. If you'd rather have me come do it for you, the first in-home visit is $99 flat — most jobs done in one trip.

Would you rather I just do this for you?

No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.

Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
