fit an aftermarket sat nav to a pajero with a Rockford amp

I'm looking to have an aftermarket sat nav unit installed in my Pajero with a Rockford amp. The sat nav unit is a Jansite Android nav unit, and I am able to purchase the necessary wiring harness and adapters for the installation myself. As of now, there is no specific deadline for when the installation needs to be completed.

I am looking for a Freelancer who has experience in car audio installation, as I would like the installation to be done properly and as quickly as possible. If you feel like you can handle this project, please let me know. I look forward to hearing from you!
