You're not going to be able to buy the software for that from Motorola. That radio is about 30 years outside the Factory support window.
There's a few different places online where you can find Radius mobile RSS available for free download, but you'll need to run something like DosBox to emulate a really slow old 386 PC processor.
Hamfiles is where I'd probably start looking for the software. You should probably also get familiar with the Repeater-builder.com Radius and Maxtrac Mobile page

For a GMRS and consumer grade radio, I would stay away from the cheap Chinese POS radios and take a look at the Midland GXT 67 Pro or the Rocky Talkie. They may not have any foo-foo bells and whistles that really don't make the radio better but, they are simple to use and of better quality than those radios produced by a non-english speaking government owned corporation in a far-away land.
There are videos comparing the two aforementioned radios that are produced by an English speaking non-government owned corporation located on the "Land of the Free".

Yes, what you are saying is true to a point.  But it's really going to depend on the infraction.  If it's linked repeater ownership... I disconnected the link and have no intention of reconnecting it.  Or I took the repeater off the air permanently.   With those corrective actions, there aren't any additional remedies.
Excessive power output... checked the programming of repeater in question and it was set for 100 watts. This was an oversite.. reprogrammed repeater to correct power level and verified power output with brand X watt meter that was calibrated on 6/2023, serial number 23252... or what ever with a E100 slug that was calibrated at the same time.  Again, nothing else to correct.  With GMRS specifically, we aren't limited to any Maximum EPR, antenna gain or height.  We just can't interfere with other licensed users attempting to use the frequency, and that's only within reason.  If you move into a house next to an active repeater site, you aren't going to be able to complain about not being able to use CH 16 if the repeater is on that channel.   Now if the site has all 8 pairs tied up, then there is the possibility of someone at the FCC considering it to be a complaint.   
Now if you are into an ERP power level issue with a commercial license, and you botched it by putting the antenna too high, with too much gain, and running over the licensed output power level to boot.  That's the one where they might keep banging away until you are completely compliant if you tell them you just turned down the power. 
 

I like the Bird 43 Inline Watt Meter

The system in question is not remotely near NYC. Its 6+ hours NW of NYC.... 

Stretches between Syracuse and Niagra Falls.  3 repeaters if I remember correctly.  I'd show you on the map but they've been removed.

I always tell those clowns that while I am an honorably retired cop, I will not contribute to them because most of these organizations speak out against restoration of our gun rights, such as "Constitutional"/ Permitless Carry bills.  Funny, they never try to argue.  They just hang up on me.  🙂

Well, Marc brings up several good points. 
I am gonna throw some more gas on this fire and bring up another regulation that I have seen pop up.  That being the requirement to listen to the channel / frequency you are about to use before transmitting.  This was to verify that another repeater/ simplex user is NOT currently using the frequency before accessing it yourself. 
Commercial radios used 'HUB' or some other similar feature that when the mike hangar (knob on the back of the Microphone) was taken from the mike clip that is mounted to stow the mike when not in use disables the PL/DPL/CTCSS tone for the receiver and allows you to listen to the RX frequency in CSQ.  This isn't a part 95 specific requirement, it's written elsewhere in 47 as a requirement for all services other than maybe HAM but I am betting it's a requirement there to.  Commercial guys know this as 'monitor'. 
No one bothers with it any more but it's still on the books.  There are ways around it.  First being the class of licensed frequency you have.  Again, going to commercial part 90 stuff, there are classes of frequencies.  These are designated by the number behind the FB, or Fixed Base designation for the licensed frequency.  FB2 is a shared frequency that has the requirement to monitor the frequency as there are other users in your area that could be licensed for that frequency as well.    Then there is FB6 and FB8.  FB6 had no requirement to monitor but may be shared at a distance typically greater then your normal coverage area.  Then there is the FB8.  FB8 is considered a 'control channel' level license.  These are allowed to transmit in the blind at all times.  If you have an FB8 license, there is zero requirement to listen first and you are allowed to transmit on that frequency at all times.  In a trunking radio system, these are what are used for control channels.  The rest of the channels are typically FB6, having no requirement to monitor but a small possibility exists that you may encounter some interference occasionally. 
Back the the requirement to 'monitor'.  Obviously we don't have licensed 'assigned' frequencies any more.  So there is a requirement to monitor before transmitting in all cases.  And how many linked repeater systems have output frequency receivers that are monitoring the TX frequency and will deny the repeater the ability to transmit if there is another user on the frequency locally?  Of course the answer is none.  And you are NOT going to be able to monitor a repeater frequency in Iowa if you are in Florida. 
And that is how we get hung on linking regardless of with part 95.XXX says.  If you are in Florida and key up a repeater in Iowa that shares a frequency with another local repeater, or someone is using that channel simplex, you just caused interference with that user.  It's also how they CAN go after repeater users that are not repeater owners. 
 
 

What?! Of course it does! How else will we determine who thinks they are the smartest?!

With what you provided in our request, no. If you stated what kind of help you neede, such as locating cables, software or something specific, then yes, someone can and will provide help. 
Now, what help do you need?"

First off no one knows my call sign around me. I dont plaster it on my vehicles nor even tell many folks I have it. It was and is still used for my familty use. Being I live in the country I really dont see neighbors calling me. Again why would I even remotely need to answer someone. Thats not why I got GMRS 25+ years ago. If I want to chat with someone I'll go to another service. Just becasue this service is now ham lite and everyone thinks they need to rag chew on a repeater or have a SHTF need for it doenst mean we all do. If the SHTF GMRS would be the last thing I was worried about.

The FTM500 is not a GMRS radio anyway. I assume you want a ham repeater ? If so many better options out there but to stay Fusion the DR2 is all ou can use. 

Many folks have dropped their links over that and other stuff. GMRS was never meant to be long distance communications. 

I run the midland mobiles in my parents vehicles as they are KISS and plug into the lighter jack.

Yeah, that's just wasteful... especially since we are limited on frequencies. 
Now I have said before that we (and hams for that matter) don't have huge budgets to select our tower sites of construct a site where we need it to minimize overlap.  But there is little sense in putting several wide area coverage repeaters on the air when the overlap completely.
When I was still in the game for linking, I was looking at fill sites.  Low power, low profile sites that would fill in specific area's where coverage wasn't as good as I liked.  But that was starting to get into heavy RF coverage calculations, high power (20 watt) attenuator's for both TX and RX so that I could limit the coverage.  The one site I was looking at had antenna's at 400 feet.  That created a problem because I needed them much lower but that wasn't an option.  Now that I have got off the linking boat, it doesn't matter so much.  But I was looking at actually building two additional sites that would have been true simulcast on 462.600 for a total of 3 sites. 

The ham world has been linking for decades, first with RF and now internet just like GMRS. They can't get a decent handle on their stuff with "experts" that tell us what frequencies we can put our repeaters on and so forth. Its worse in the DMR side with hams. I dont see GMRS being any better if linking continues to happen. The simulcast systems that are out there and were out there where built by good techs and folks who know what thye are doing. Not everyone has access to Quantars, TRAK units and MLC 8000 simulcast stuff but some do and know how to setup a system. 99% of the GMRS community does not. We can't even get folks that do link repeaters to set levels right. As much as I think a true voted/simulcast system should be acceptable on GMRS (and was common before the ham lite crowd hit the service) I think all linking should be dropped from the service. For decades GMRS users used the service to do what they intended it for. Its only been the last 4-5 years its turned into this. 

The industry standard handheld in UHF is 4 watts. Thats been the standard UHF LMR radio for as long as I have been in the field. All more power from a handheld does is drain the battery quicker. 

Wow, I didn't realize that my comment sparks a grammar war now too (lol)

Ah Hah - Just shy of 3 watts with just about 1.12 or so:1 on Ch. 1, 1.15 or so:1 on Ch. 20, and almost but less than 1.2:1 on Ch. 40.  I think my problem is solved now and I am a happy Jeeper. Both my Telewave and my DOSY are pretty close and good enough for hobby work.
And this check was with the engine idling with 13.21 VDC at the battery.

The problem was the plastic bushing was installed under the mounting bracket instead on top of the mounting bracket and the cable was not grounding to the  mounting bracket.
The cable mounts to the bottom of the mounting bracket.
Now, maybe I didn't need to order that 2-30 MHz Bird slug now, OH well, at least I have one now.

I have to agree that using a dedicated repeater with a quality duplexer is the way to go. Our club is using a Bridgecom repeater setup for GMRS and we went with a separate duplexer that one of our members tuned using the proper equipment.
Mobile radios just can't handle the high duty cycle like a repeater can. Plus here is the defense issues with having antennas and radios close together. Using a cheap duplexer and cheap/wrong type of coax cable will make the problem worse.
@OffRoaderX tried using two Wouxun KG-1000G radios and he went to a dedicated repeater since he was having issues when using two mobile radios. He can definitely give you insight on this. 

My suggestions besides getting a quality duplexer like a Celwave or EMR Corp. duplexer, is scrap the idea of using two mobile radios that were not designed for a continuous duty cycle and a multi-radio environment and get a real repeater and save your money, time, and energy.
