I have try to change it but not successful as my less skill
because program can't run after that
if i try to repack to apk this apk will not able to install

I want to try to change this because I think
Nuvi A50 Phone can show Thai JVC, B1130 is part number of A50
and in nuvi old system fake part number can help you to unlock some function

If my think is wrong then no point to try to change this value.
