    3+ years ago, I upgraded the stock 57010 unit in my 2013 Prius V two to a 57011. The main reason was I needed Navigation, and HD radio. I was able to find an aftermarket GPS antenna that fit nicely behind the air ducts above the unit, and has been working fine. I had no desire to get XM at the time, and my car being a two, does not have a Sat antenna on the roof. Also, my car being a two, I never got contacted by Sirius XM about any trials.

    OK, in June of 2021 I buy my 2017 Prius V, but keep the 2013 as my Uber vehicle. 30 days later, I get a call from Sirius XM offering me a free trial. OK, I'll take the trial, but the 2013 Prius V two with the 57011 is the Uber car for now, (at least until it hits 150k) I want to use the free trial on the 2013, and I was told I can use it on both cars. Problem: the 2013 has no antenna. I believe that an aftermarket XM antenna can be placed next to my GPS antenna.

    OK so I recall that the jacks for the Satellite and GPS antennas on the back of the 57011 unit were of a special kind. I don't have time to pull the 57011 out this week, and I'd like to order a cheap aftermarket XM antenna on eBay for the duration of the trial. I'd like to avoid pulling the unit out twice.

    One other consideration:

    The 2017 Prius four has a 510165 unit, which is very similar to 510057 "Facelift" unit used in Kapik's great thread on upgrading from a 57011. When I drive it, I find myself getting spoiled by having both the radio and radio displayed at the same time. While Ubering in the 2013, I leave the "Maps" view on by default. This is how I know what street I am driving on, and what the next street is coming up. Every now and then, I want to know what song is playing, and I briefly switch back to radio. I think I will eventually upgrade to the newer unit. The "Facelift" unit even has a small icon on the map that is a Compass!

    If I keep the XM radio subscription, I may want an aftermarket antenna that fits "Facelift" unit. That may mean buying a different aftermarket XM antenna. That is OK if I need to do it.

    I think I would just get the xm app on your phone and bluetooth it to the 2013 radio. You can still use nav. Plus there are many extra channels on the app and the use of the app is free with the 2017 subscription.

    Thanks for suggesting that. I did not know that the phone was an option.

    The phone I use is an 5+ year old Galaxy Note 5, and I am already using it for a lot of apps simultaneously (Lyft + Uber + Google maps + a few helper apps, + sometimes Doordash). Adding a streaming app to the mix would make things more complicated, and slow the phone down even more.

    There is a complicated reason I have not been willing to upgrade the phone, which I won't go into.

    If you go forward with a standard xm antenna, you will need a HFC to SMD adapter. I have linked one below adapter cable that one reviewer modified to work. Years ago when I had xm reception problems. In my case it was factory installed xm with problems caused by the antenna base. The antenna base is actually a low noise amplifier/preamp which is required with relatively long coax runs.

    Automobile satellite receivers (SDARS) are able to receive signals from satellite-based and terrestrial transmitters at the same time. In downtown areas of big cities, xm is transmitted locally to ensure reception even in parking garages or when satellites are blocked by buildings.

    The antenna base on my car has three coax cables to the mfd - satellite xm, terrestrial xm and am/fm. The radio also sends power to the preamp. These details are not well illustrated in Toyota's wiring diagrams beyond specifying a SDAR, Main and Sub Antenna. Toyota's parts catalog simply shows the cables.


    (According to one review, this was successfully adapted to fit in the mfd's blue receptacle)

    The pic with the HFC Female is the factory connector that plugs into the head unit.

    PC does some strange things with Amazon Links. Anyway, I found the adapter.

    I am beginning to think getting XM to work in my 2013 two maybe more work than I can justify for a 2 month free trial. When I first got the 57011, I got the GPS to work with a simple $18 aftermarket GPS antenna, which is located under the dash. I was hoping it would be that easy to connect Sirius XM.

    I could easily set it up in the 2017, which my wife is the main driver. She stays out here in the Northern Suburbs.

    Doing Ubering, I definitely hit tall buildings in Center City Philadelphia. One of the three Nightclub hotspots where I regularly pickup passengers is deep in what I call the "Comcast Forest". Tall buildings would also cause problems with any phone based streaming service. I am just glad that the "Dead Reckoning" in the car GPS never lies about where I am.

    Follow up clarification:

    Assuming I bought a generic SirusXM Antenna such as Amazon item ID: B08QD45574 for $17.99, I would still need to buy the adapter you mentioned Amazon item ID: B01AQXR1C0 for $13.78.

    The antenna would plug into the bullet shaped end of the Adapter, and the gray square end of the Adapter (with some modification) would plug into the blue connector on the back of the MFD/radio unit. I am guessing this would give me access to satellite only Sirus XM signals, no FM backup. I am guessing that the white connector under the blue connector that has two coaxial connections is what the Toyota shark fin antenna would plug into (FM+SAT).

    If that is correct, it would cost about $35 for a free trial, and it might only get decent reception out in the suburbs. OK. I would have hoped that somebody sold an inexpensive XM antenna with the square connector already on it. I looked, but did not find, it may still be out there.

    Qustion: if I upgrade to the "Facelift" 510057 model MFD/Radio (from a 2015/16 Prius V), I recall that it needed different connectors for SAT and GPS. Would the bullet connectors be the correct type? Would a different adapter be needed? I am really getting spoiled by the side by side display on the 2017, so this could happen to the 2013 someday.

    When I was looking for an GPS antenna at the begining of 2018, I had many choices of connectors, and the one I bought fit if I pushed it in hard enough. For $18, and the $120 I paid for the 57011 unit, I was overjoyed.

    Another option for an adapter cable with a minor modification. The mod is illustrated by the retailer with a pic which adds credibility. The green connector is called a HFC II.

    I believe this company could also provide an adapter for the newer radio.
