EDIT
Until now source.android.com is not update with the latest download instructions. If I use the command suggested by "Landervdb" then it works. I also found some more resources for Android source code. These are given below.

Android 4.2 Jelly Bean is a version of Android. Google was expected to announce Jelly Bean 4.2 at an event in New York City on 29 October 2012, but the event was cancelled due to Hurricane Sandy. Instead of rescheduling the live event, Google announced the new version with a press release, under the slogan "A new flavor of Jelly Bean". Its predecessor was Android 4.1 Jelly Bean and its successor was Android 4.3 Jelly Bean. The first devices to run Android 4.2 were LG's Nexus 4 and Samsung's Nexus 10, which were released on 13 November 2012. Android 4.2 latest release on October 7 2013 as android 4.3.1.
Folks, I'm feeling like I'm missing something... really. I'm 100% noob in all Android stuff (please remember that, I don't understand all that complicated android terminology), so here what I got. Verizon Galaxy Nexus 4G LTE. I bought this smartphone from a friend of mine, it wasn't rooted (or how do you call that things?) or anyhow modified. I didn't do anything with it also, therefore smartphone is the same as it was when it was bought from Verizon.
As far as I can see, I was supposed to get update for Jelly Bean. But still there is no update. I still have android version 4.0.3. That's quite strange, don't you think so? I've tried famous trick with Google Services Framework many-many times, nothing. I tried to switch between WiFi / 3G/ LTE, restart / clean data / force stop / visa versa & do all the things that were supposed to help force upgrade, still nothing. I tried some codes with symbols like *# to force update (don't remember the exact code), not working.
So, the only chance to get the update is to (1) unlock the bootloader, (2) install Google's official 4.0.4 android version (factory image), (3) check for the system update and, finally, (4) get the 4.1. update, directly through the smartphone's system settings.
Hi I purchased Poweramp and have used it fine (no issues at all) on my earlier car head unit (i.e. stereo/satnav/etc..) running Android 4.0.3.
Now I have just bought a new car head unit and on getting to google play store, to try to get it installed on this new one - it says it is not compatible with this device! This one runs 4.2.2 Jelly bean. What can I do? Please help
