Ok after a couple days using the radio, like i said before the SD card is recognized,when i browse it has my song and album listings, and it plays from where i left off If i eject the SD card and reinsert it the radio will swith to that device and everything still works great, and it starts playing from the first song on it. But the USB drive will not automatically switch to it when inserted, if i go to it manually it shows that there is a drive there and recognized but nothing to browse and search for songs. So then i noticed that the play button is highlighted, so i touched it and it started to play and then i could browse and my songs and albums are there. if i remove the USB and reinsert it, i have to do everything manually again before it will play and my music shows up and it will play from where i left off even upon restarting the vehicle.So for some reason it doesnt work the same as before but the SD card does.
I like that the start up screen stays up longer ( before the update if i didnt move really fast the screen was gone and i wondered who can move that fast,haha) so i can select if i want to turn on the heated seats or Steering wheel ,its still been in the 40's in the morn but the auto heating doesnt work cause its out of the 30's.
So far the clock seems to be staying right on time with my Iphone but its only been a week. But it would be slow on time within a couple weeks before. The only reason i noticed the clock problem was cause after having the Jeep for a few months i noticed i was getting into work a little later to punch in, and then i saw a posting on the forum about it too.
The local radio station I like still seems to tune in better and sounds nicer.
The other minor issue i noticed is sometimes if i go to turn up the radio just after i have started the Cherokee and the startup screens have cleared it will not respond well and then it will go up quickly in volume without my hand on the volume knob, its actually gone up in volume then as im shifting to back out of the drive, Didnt notice this before and ive always done this (Gotta hear my morning show DJs).
Hope everyone else is having good luck with their update.
