Newbie with radio issue

Firstly hello to everyone and thanks for taking the time to read this post.

As you can see I'm a newbie and this is my first post on priuschat, i am in London England so for the records i own a toyota Prius Plus / Alpha as it is a Japanese import. so let me get straight to the point.
i recently went a purchased a used original Prius radio/navigation system model panasonic 59014.
after figuring out all the terrible connection made for an aftermarket radio install i managed to get back to basics and install the original toyota system but the issue i have is that the system is not outputting any sound, i have triple checked this and can verify that it is the system at fault and not any wiring so my question is this, does anybody know how or if it is possible to fix such a problem with the unit and is it an easy fix or something not even worth attempting.
cheers for any help provided.

 

Hi sorry maybe I've made it sound confusing.

The car came with an after market radio which works but was not original to the car and i wasn't happy with it.
I went and purchased a original toyota radio one that would have come standard with navigation n the car from the main dealer but when i installed this system no sound would come out of the speakers at all and i tried all the tricks in the book to see if the wiring was at fault or the system and i found it to be the system at fault and its not out putting sound at all.

so can this system be fixed so it does output sound or am I'm up a creek without a paddle

cheers and i hope this makes it clearer as to the issue.

 

no it doesn't have warranty i purchased it from the net its second hand, just no sound

 

yes tried it as i thought about that but nothing.
hooked up external speakers to make sure it wasn't the wires playing up and noting at all.

 

Everything else works exactly as it should just no sound.
thanks for the replies and yes hopefully someone might be able to shed some light
cheers

 

i was thinking about an external amplifier but i had a look under the seats and noting at all and also i don't have a loom connection in the dash for an external amp so it definitely has an internal.

i could look down the return it route but you know what its like sometimes the money you spend on returning an item over distance and the weight of the package outways its worth and it can be cheaper to get it fixed in this case if possible.

i think seeing as everything other than sound works it would make sense to try and fix it

 

Also it doesn't has a JBL system.

 

Thanks for the replies so far on this.
i will upload some pictures of the exact system i have and if anyone knows the internal working and how it could be fixed then that would be excellent
