I'm going to answer My own Question because no one else has - so I did researched the answer.
How to Set Radio Presets:
Press, Set RND, button.
Display will show.
Select, Set 1, for 1st time. I believe by just pressing, Set RND, again.
Assuming you have already selected your station (?)
PRESS/HOLD down, #1 Button, UNTIL display shows time.
If you just press #1 Button QUICKLY, it will NOT be stored in Memory.
(P.S.) Beware of YouTube video with older man in 2010 Jeep instructing Presets, as he just hits the Number buttons quickly - which will NOT - be Memory Stored.
*Note: Although there are only (6) Numbered buttons below the Display, you can Memory Store up to (12) Presets, by Selecting, Set 2. Therefore,
AM has (12) Presets
PM has (12) Presets
SAT has (12) Presets
**Note: When in, Set 2, Mode, Pressing #1 Button, will Display #7 on Screen, and Pressing #2 Button to Preset, will Display #8 on Screen, etc.
IMHO I think designer should have labeled the, Set RND, button,
but that would make sense of course LOL and a BEEP sound when Station is Stored in Memory, would also make sense. I have to say, the Asians definitely have gotten it all together, as my prior Toyota was completely intuitive.
I still am clueless as to the acronym RND ??? However, since the Vowels are missing, it could stand for the word, ROUND?
But, Set Round, also makes no sense. Aaaaaaaaaaaaaaaah. Only consolation is that Jeep is Not American owned - so it seems the blame goes toward the Italians. haha
