Then there is one similar model that I checked at a shop in Rawalpindi (I hope you live nearby this area) about 3 months back.
The unit was English language supportive and in very good condition along with access code/card.
I believe back end is similar to yours, in that case if you either exchange your unit with that on terms of paying the difference amount or buy it on total payment, you can easily replace your existing player without the need of any sort of alterations in wiring.
Just give it a thought, and if you are interested I will share further details of the shop and you may try your luck.
