The manuals have the Kenwood part numbers you need. Then try searching on places like ebay for them.

Very unlikely. Two different services and the frequencies are hugely different. You should read the past threads on this forum about the possibility of buying a multi-service radio. The probability of the FCC allowing that is zero.

That was earlier in this thread 😝 around the middle of page 1, and there's a link in the last post on page 1, but here is the post again:
 

@Sshannon, @FreqieRadio Sorry for the brain fart. I should have put that together.

There is a bunch of repeaters around that area. Join the site and you’ll have access to the tones. 
 
edit- it looks like a bunch are permissions needed but once you join and are logged in you can request permission. I would hope that it would be granted as this is a perfect use case. Good luck and if you decide to join welcome. 

The GMRS Pro handheld radio is capable of sharing its GPS location with other GMRS Pro hand held radios.  I think the OP is asking if there are mobile radios that are compatible with the location sharing feature.
@FreqieRadio:  Digital data, such as location data may only be transmitted by handheld portable according to the GMRS regulations:
(d)Digital data.GMRS hand-held portable units may transmit digital data containing location information, or requesting location information from one or more other GMRS or FRS units, or containing a brief text message to another specific GMRS or FRS unit.

Yeah, I got involved with a forum that started as outdoor warning siren techs and manufactures.  We would exchange info on different things we had seen, odd issues that we couldn't figure out and crap like that. 
Then the 13 year olds took it over.  And they wanted to discuss leaning poles and what specific frequencies the sirens operated at and all sort of nonsense that had no bearing on keeping them running.   Then of course they started disagreeing with people.  Once case the guy that dude was arguing with was the guy that designed the equipment in question.  He was the designer for that manufacture.  And this clown is arguing with him about what he's saying about the equipment is incorrect. 
That was the beginning of the end. All of use that were in the industry left.  And it was a shame, because at one point it was a very helpful took to reference.  Now, not so much.
But I actually am tired of stirring the pot. And any more, there is no need to stir it.  It just happens on its own.  And again, it just gets boring to see a horse beat to pink slime.
 

it might be the "fun" button that selects the mode, once you're in that menu.
From there, all you REALLY need to do is dial up the correct repeater channel (the base 30 should be there in gmrs mode) and enter the transmit tone. The instructions @WRXE944 linked has how to set the tone on page 14.
 

Looking for the post right now (may have been another thread), but I was corrected that it's holding the v/m button when turning it on that will give you the option to change modes. Be aware it does wipe any channels you program when changing modes, and for gmrs mode, reverts to the base 30 channels (22 simplex, 8 repeater).
Edit: found it.

All the good YouTubers talk very slowly and deliberately. 

I never compared them.  However, I did use the UV-17 on a road trip, and it worked okay between two cars about a mile apart.

That’s from 2014, but thanks for the nostalgia. My point is still valid, agencies should be reorganized and made to operate more efficiently and with purpose.

First off, I never said that keeping unauthorized users off a radio system was the only reason for trunking.  But it WAS a sales point. 
Never heard of people using 'illegal radios to access a trunked system'  Maybe not in your state... Ohio has had several instances of people being busted for selling radios that were programmed for the state wide system. 
Never heard of it prior to trunking?  I have worked with the FCC and in one case the FCC and FBI tracking someone that was interfering with repeater systems that were County EMA equipment.  All EMA's fall under Homeland Security.  And due to that screwing with them can be considered a terrorist activity.  And that's not some guess or interpretation, that was directly from the agents I was working with. 
We also figured out that the radio that was being used was indeed a cheap import.  The 'roger beeps' on those radios are distinctive and the logging recorder that we had running did hear that specific set of tones multiple times in the case where the FBI was involved.  The other times were fire and police repeaters that the FCC came out and tried to hunt the person or persons down but had no luck, other than whoever it was stopped doing it.  But it was made public in the radio communities that the FCC was in town and that is what seemed to make it stop. 
Back to the trunking thing.. Yes, the primary reasons for trunking systems is frequency management and sharing.  But interoperability, access control and radio resource management are also big parts of it too.  And wide area coverage beyond the county level is a big piece of it was well.  You simply couldn't use a single frequency across three or more counties that contained any significant population. 

And this thread ladies and gentlemen is why some of us that actually work or have worked in the communications industry and might know a bit more about these topics than the casual user tend to steer clear of posts like this and giving technical answers to questions.  There is always somebody that thinks that someone told them something else that they have ZERO first hand knowledge of will argue with guys that do this crap for a living.  It gets old.  And is one of the reasons that guys like me no longer bother with these forums like we did. 
But here's the sad part of all of this.  There are some on here that DO know.  And when they get driven off of here due to the BS, you loose that knowledge base. 
 

Welcome!
Rule #1: Have fun and don't get too hung up on the small stuff.

Might just have been bad luck. I had a buddy who purchased a UV-5R and bugged the cops at the local jail with it. When he told me what he was doing I told him to immediately STOP, that’s how you get caught and burned by the FCC.
He did. Later found out the FCC was in fact trying to track the source down. Now he’s a happy licensed, after some encouragement from me, a Ham and GMRS user. He learned a valuable lesson without the high cost.

The simple answer is our government has become too big and needs to justify its existence with endless regulatory nonsense.

It’s time to scale back all federal agencies and re-organize the ones that remain. The FCC is no exception.

With and attitude like that why bother with rules at all? That’s until someone else’s attitude stomps all over you ruining your ability to use the services. 

I suppose someone who wants to do this can do what an overwhelming number of people have... buy a quality radio that does everything and keep your mouth shut about it. If you don't tell anyone, no one will know.  Don't cause interference, don't be an ass, and don't go on frequencies you shouldn't be on, and you're going to be fine... not that I am making any promises or condoning violating the rules.

Looking at the chart in the manual, it looks like DCS #27 equates to a DCS tone 165....since it's specified as (N)ormal, that should be the one you need.
If it were (I)inverted, it'd be looking for that chart @Sshannon mentioned for  an equivalent tone to use, then using the chart in Midland's instructions to find what code to enter. I won't say Midland is bad, but their use of code numbers to enter the tones does add an extra layer of complication.
Also, some of that reputation online is based on prior versions of the radios, which WERE less than stellar for repeater use due to being narrowband only (which sounds quieter on a wideband repeater) and not having the ability to set transmit and receive tones independently. As far as I know, those shortcomings got addressed when they updated the radios from a usb-a port on the front to usb-c.

No, 65 is not the same as 165N. 
Unfortunately some of the manufacturers have included non-standard digital codes. Scroll all the way to the bottom of the list. 
About the “N”, that means normal. If you see an “I” it means that the bits of the code are inverted. 
There’s also a document “out there” that reveals equivalent codes. It has been attached to forum posts in the past. You might find it in the files section. 

What that's saying is if you just want your signal repeated from that repeater, only use one tone, and if you want it repeated across all of the other repeater sthat are linked to Shawbute also, use the other tone (the "for link access" part.
In either case both of those are the transmit tones, and you will not use a receive tone, as the listing is saying the repeater does not send one.

The Shaw Butte repeater is linked with the Southwest Community Radio System (SWCRS) network of other repeaters throughout Arizona, New Mexico, Texas, Colorado, and I think Utah. The Shaw Butte repeater has two access modes, one for the local mode only, no link to the network; and one for the network mode to link up with the other linked repeaters.
The linked repeaters in Arizona are Shaw Butte, Towers 600, Mt Elden, Diamond Point, Greens Peak, Pinal, Mt. Lemmon, and others. The DPL code is for the linked network access and the local mode requires the CTCSS/ PL of 100.0 Hz. There is no tone on the downlink side.
If you want to communicate with other stations near the other repeaters both stations would have to access the respective repeaters with the link tones. Also, if you want to participate in the Sunday and Wednesday Nets, you'll have to access the network with the link tones.

Have you tried logging into the site where the repeater map is? Even though the forum and the repeater site are both Mygmrs they act as separate sites so you’ll need to sign in to each. Even if it’s an open repeater I believe you still have to log in to see the tones. Hope this helps.
