I don't know of any aftermarket solutions for adding an aftermarket receiver. I know @Jimmy07 makes custom harnesses to integrate factory upgrades but not entirely sure if anything like that is needed to upgrade from the 5" to the 8.4" or 12.1".Did you do this? Do you have any info on harnesses or aftermarket radios that can be used? So far I have only found a company in the UK that seemed to have some answers, but unfortunately they don't sell directly.
