Technical questions - 2015 Grand Cherokee Overland

I just got my 4th Grand Cherokee today, a fully packed 2015 Overland.

I have the Model RA4 radio, I've always plugged a USB stick in for my last 2 GC's to transfer .mp3 albums over. This takes a while because I will have 150+ albums to get saved and a 32GB USB stick.

Question: can I plug a laptop directly into the radio instead of a USB stick? If this is possible, is there an app for doing any customizations of the system or file transfers from the laptop?

Related, are there any such custom skins/themes for the heads up display, like a speedo dial with the digital MPH inside of the dial?

Pretty sure you can't transfer music over to the storage on the radio. You can plug in an SD card and leave it there though.

So, they've taken away an option? There were hard drives in my last 2 radios.

I thought it was strange there was an SD slot, since SD is no more popular than any of the other memory types.

I think its because SD cards are so huge now there is not as much of a need. a 128GB card will hold quite a few songs for 30 bucks. I'm not sure what the card limit size is for the GC, 32 was more than enough for me

2014 and newer Grand Cherokee's don't have a hard drive. Yes another thing they removed, in addition to cool CD player behind the radio, real buttons for heated steering wheel and heated and ventilated seats, and flipper glass.

Re: Technical questions - 2015 Grand Cherokee Overland

I was maxing out the previous HDD, so a 64GB would be an improvement there. My entire music collection is only around 70GB, and I only put certain albums in the Jeep.

Do you think an Ultra High Speed BUS would help, since the music will be on the card?

No. Even lossless music formats still create file sizes and bit rates that fall well within the slowest card speeds.

Even USB 1.0 is plenty fast enough.

2004 - L6 Special Edition in Lava Red/Black
2010 - V6 Laredo X in Black/Black
2013 - V8 Overland in Black/Light Beige (not my choice, I waited too long)
2015 - V8 Overland in Black/Black

I had been thinking Summit this time, but I have 95% of the same options, and I like the wheels & trim on the Overland better and it was a few thousand $ cheaper. And since I can't really afford an SRT, the Overland will do nicely.

Amazon has a Sony 128GB, Class 10, UHS-1 SDXC 70MB/s for $29.98, so I got one of those.

I guess if a hard drive can fail, using an SD card makes it easier to replace a bad one and easier to upgrade too.

I see it more as a more convenient means to put music on them. Remove it, take it inside to your computer, put the music on it, then put it back in the Jeep. No need to do it in the Jeep.

In theory, too, you could use smaller cards to rotate mixes of a fewer number of songs so the system isn't always playing the same tracks, which it seems to do. On a 3 hour trip, it will hit one song several times while leaving plenty of others unplayed. The random play function is crap in the Uconnect system. Then again, so is the default player in Android.

Purely for the issue of plugging in a laptop.

Commercial PCs, particularly laptops, only come with cheap USB controllers that
only know how to be the initiator side of a USB connection, not the target.

There is hardware that can switch roles between host and device types, but it tends to be rather specialized aka a tad pricey.

No HD in the radio to transfer content to...

Initially I put my stuff on large SanDisk USB's but since then have found it slightly less of a pain in the neck to split the content across genre specific USBs just to make it easier to find/play the selections I want to hear at the time.

Re: Technical questions - 2015 Grand Cherokee Overland

I seem to remember the 2014 Summit I test drove last year had a red color in the instrument cluster when it was in Sport Mode.

Is this specific to the Summit, or another discontinuation? I wouldn't mine this as a custom skin/theme. All I see is the green flag symbol.
