I've searched, and I couldn't find out how to do this.
JUST KIDDING!!!!!!!!!
Just wanted to thank you guys for the hacks, mods, instructions, and maybe more importantly, laughs. I got my F90BT yesterday (from 6ave, another forum recommendation - another thanks), hooked it all up in my 2001 Hyundai Santa Fe, and everything is working like a charm.
Special shout-out to Maverickster - Your Hardware Bypass For Dummies should be fucking published!!! Biggest help ever!!!
Again, thanks to you all. If this were a fubar lounge, I'd buy you all a drink.
