Question about Kenwood DNX7100 Car Video Player

4 Answers

Usb drive just installed the new dnx 7100 pluged in my usb drive and it wont see it, it just say no device. is this because i am using a usb portable hard drive and not a usb flash drive. I was told by the guys at ultimate electronics here in az. that it would work with this stereo that is one of the main reasons i bought this one. I am happy with it so far but i would really like the usb drive to work. Its a 160gig drive. could that be the issue should i get a smaller one or just a flash drive. the idea was to have all my music with me and i dont want to have to spend 300 dollars on an ipod.

    I am having a similar problem... I have the Kenwood 7120, had my 320gig HD working just fine. Then I deleted some songs off it and the 7120 would not see it any more. I know for a fact that portable hard drives will work as mine was working just fine (a lil slow because of its size)... I tried erasing every thing off it and starting fresh, but still no luck. This is a fairly new problem for me (just happened yesterday) and I am still troubleshooting it... Any one have any suggestions?

Another solution here....I have a Kenwood KDC-x991 deck.

Have USB Read error problems..
Anyway I had a 30gb hdd, replaced it with a 100gb (according to manual, will use up to 120gb w/out external power...)
Anyways long story short, the 100gb drive worked fine for....20-25 mins...
I was happy. Now here's the clincher. After 20-25 mins, it gave the USB read error. (instead of resetting the deck and have to make the date/time/eq/sound/setting changes I unplugged the USB drive...changed source from USB to tuner (or anything else for that matter). Then switched back to USB w/ no device installed and after 2 seconds or less, the USB Error disappeard and said no USB device connected....Anyway thats the best way (I've found) to get around the Resetting the deck. Anyway after that from then on I could not get the Hard drive to work for more than 30 seconds. It would play then give me the read error.

Tried a different drive...80gb same prob...went back to the 30, and it was fine.
Tried a 160 (I knew it wasn't going to work) and it didn't either.
Anyway was thinking what to do.....most of the USB external drives I had came with a power port on it aside from the USB port plug. Or the drives came with the Y Cable....
The long part plugs into the Kenwood deck, and then the END of that cable plugs into your USB external drive, and the small piece connects to a (get we gooooo FTW) USB to Cigarette adapter!!!!!
And this worked like a charm on ALL my drives. Stable...and just plain worked great!
Anyway I hope that this will help you guys w/ your usb probs!

I don't know about the DNX 7100 but I just bought a Kenwood P-NAV 512 (KVT 512 w/navigation) for my truck and a DNX 8120 for my wife's 4 Runner and both will play from a 160 gig usb WD Passport hard drive. I bought 2 WD Passport hard drives from Best Buy for about $80 each.

Most portable hard drives that run with no power cord get the power from the USB cable. If the hard drive requires more power than the DNX7100 can provide, it will not power up properly and not be readable. It may take some testing with different drives to see which one(s) will work.

The USB drive has to be a Flash drive (they make 16GB's now) not a regular hard drive, i tried the same thing and it also did not work i asked Kenwood about it and they said that it is only made to read flash drives and first /second generation ipods (regular, video, and nano) not able to read 3rd gen., but software upgrade should be available soon. Thats what they told i hope this helps.

Hi I have an apple mac laptop and have plugged my new iomega 320gb 2.5 select portable hard drive. The problem is im trying to drag movies accross however it wont let me?

Portable devices such as USB disks (in most UNIX based operating systems) will be mounted as READ-ONLY. Remember the old floppy disk with a slide switch to make them READ-WRITE? same principal.
Try right clicking (MAC uses double finger click together) on the Desktop Icon that appears after you plug in the USB drive... is there an option to select READ-WRITE?
let us know if that was it.

When I plug my seagate free agent go portable hard drive (250 gig) into my usb, it register's that there is a device pluged into the computer (give's me the DING, that window's is famous for) but say's it...

try a different usb drive. if you are using win 7 or vista uninstall that device driver you downloaded. if its xp re install your usb drivers from the windows site just go to your device manager
win 7 vista click on computer sys prop device manager see if drive is connected hit update driver or roll back. same with usb system on win xp right click my comp. go to prop, then device manager let me know if this helps. but really important to make sure that you are plugged into a usb port in the back of the pc not thru a hub

Computer wont read portable hard drive

An external storage-device has four major components:

* the USB cable

* the power-adapter

* the disk-drive inside the enclosure

* the USB-to-disk-drive adapter inside the enclosure.

One of these components has failed.

Try a different USB cable.

Try connecting to a different USB port on your computer.

Try connecting to a USB port on a different computer.

Take a "multi-meter" and measure both the voltage and amperage output from the AC adapter, and compare with the specifications on the label on the adapter.

Open the enclosure, and remove the disk-drive, and then connect it as a "slave" disk-drive in a desktop computer, to see if it works at all.

Purchase a new, compatible, disk-drive, and install it in the enclosure, to "revive" your external storage device.

Get the part-number and serial-number from the label on your disk-drive, and access the manufacturer's web-site, and use "check warranty status", to see if they will replace the device, at minimal cost to you.

Note that W.D. has a "Customer Loyalty" program -- you can buy a new W.D. device, through the W.D. web-site, at a significant discount.
