My 2010 wrangler unlimited touch screen radio doesn't work half of the time. does it have a short

check battery, does engine start.
do the head lights work keys in pocket?
battery voltage is 12.6v, rested, is it? key off.? all things off.

wiper run key off? or on?
park lock out, is a whole other matter.
1st is battery , always. 1st, (they can discharge)

i cant understand your post. "have time" and (it wont come on) and
or you can use touch, << did you mean Can't ?)
tell that which works and does not. (
media center 730n? this failing
with Navigation?

get it serviced,?
this is what we call the magic features, Uconnect.
(window dressing bad?)
DIY ? what are you asking?
Help to do WHAT.?

or check fuses.
is car battery charged to 12.6vdc rested???? or at below 11v.?
does car run and drive? perfectly,

in the shop, they checks fuse, and battery voltage.
then they scan the PCM for errors, if they have errors the fix
that first. like bad comms to u connect/nav, radio , ,etc.
then work up to the actual head. finally replacing it.

these are fancy , complex to the max , high end options.
and when they bust are expensive to fix. '

my guess is you have this system.?
AM/FM (1-CD/DVD/MP3), full map navigation (6.5" integrated touch screen display), 1-disc data drive,
integral satellite & input jacks (RER)

"These radio receivers can only be serviced by an authorized radio repair station. See the latest Warranty Policies
for a current listing of authorized radio repair stations"
this means very special tools are needed to fix the unit
and access to special software updates in the unit.
go to the dealer an get just that.

THERE IS A RELEASE BUTTON THAT YOU HAVE TO HOLD IN THEN JUST LIFT UP ON THE HEADREST

This would be a diagnosis for a Chrysler tech at a dealership as they would have the correct test equipment and training to diagnose.But if I were to guess my first thought would be the telematics module.

Circuit board or a resistor

Are you check fuses? and harnesses connections.

look into a radio repair shop or just get a after market radio installed at a audio store best buy-etc

I suggest you have the dealer look at this, you can't get parts for the AMP as GM doesn't sell them to the public just authorized repair shops

Do you still have warranty left? If so bring it into the dealer for service. Otherwise if you don't have any warranty left there is a software update the dealer can do that may fix it, if that doesn't fix it, a new radio is around 1900 dollars.
