i just de branded my c702 for free. i used a few different sources.
1. [Debrand] A2 (Db3150) Tutorial - Top Sony Forums
this walkthrough is great. but you cant use the link on it to generate the customize_upgrade.xml file cause its not supported, but i found the details of how to make the file here:
A2 Cda And Debranding - SE-NSE Forums
its fairly easy, and my GPS still works.
