Google is not correct. NMO30 is the Larsen part number for the antenna (whip and base coil). The magnetic mount would have a different part number such as NMOMM or NMOMMR. Many sellers may combine the antenna and the mount and sell them as one SKU.

To anyone looking to acquire commercial radio programming software:
Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.
If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.
To obtain Motorola software see the Sticky in the Motorola forum.
The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.
For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).
This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

But needs 64” whip to tune.

Pursuant to the notion of "leave the tuning to the experts," has anyone tried the President antennas with President radios? The President Iowa CB Antenna, for example. Maybe the Alabama would be better, 5/8 wave vice 1/4 wave.
I'm thinking about it.

Texas 1800 with Lincoln II+ for my pickup.
(Oversized puck to mount anything). 13’ clearance makes it city friendly. Different radio would still be President as accessories chosen are of that brand.
Other reviews of this brand antenna I’ve seen state the usual (not tall, etc), but like the quality. Choose well. Height lost is performance lost.
9’ quarter-wave is the mark.
IMO, 5’ is the minimum for performance.
To get a start with minimal trouble I’d try the 66” Driver Extreme, or the 5’ Skipshooter (clear or natural color). Top-load is easily dealt with. (See tuning data for each).

I note that there is also an NMO27 by the same maker. What is the reason or advantage to using the NMO30 instead of the NMO27?

There is a decent amount of discussion about this question in this thread:
NMO mount antennas
I recently switched to a NMO mag mount antenna on the roof of my PU truck. Installed a Larsen NMO CB27S with the 49” whip. This antenna is getting terrible SWR on 11 meters with a 49” rod length. Not like the Wilson 1000 I replaced with it. I was getting 1:0 SWR across the band with the Wilson...

Wireless Speaker/Mic
Another option. While I’m no fan of giving up SSB, I understand the appeal of a radio this size. (NRC equipped, of course).
“Might” be that using this mic and attaching to one’s shirt or coat collar to listen while mobile gives passengers some relief.
NRC on TX may be an aid with these (test).
Not Bluetooth. DECT, like wireless telephones.
Out of production, but can still be found.
My pickup has one at ready to swap from other mic used.
Testing wireless mic (BEARCAT 680)
Note how far he’s gotten from vehicle. He’s also in a location with plenty of potential QRM.
Mounting such that distances are maximized is part of an installation for its base unit (antenna). Do a few tests before final install.
The quality of your radio gear & installation will play a significant role in the performance of a wireless mic when at a distance.
I fail in understanding why these weren’t more popular for mobile: there’s almost always a reason to examine that which concerns several from atop vehicle hood or up a slope, perspective, which literally defines the usefulness of radio.
Scooting in/out of the vehicle for RX/TX ain’t the way to go.
Engine-idling — maybe a dipole tossed up in some trees — makes one’s vehicle a powerful mobile station. Atop a hill and wandering around a bit is how this tool adds a real margin of performance.
When one hears, “yeah, CB ain’t worth a flip”, it’s from ignorance, first, and failure to live up to applying amateur operator standards, second.
So, . . . while the above may not seem applicable today, tomorrow has all sorts of other potentials.
Save one’s self & his vehicle is one part. Ability to use his vehicle at all is another.

FM is nice here, for the few good people. modulation is great, but just time until the idiots cash their SS checks to buy a FM radio. But for now FM rocks here.
