I'm new to the site, but the info has been great. Just had my F700 installed but I did the hardware/software mods myself. Works great!! However, the parking brake light stays on all the time. Is this normal ops? Also, I decided not to go with the PAC SWI-PS for OEM steering wheel control. Now I'm second guessing myself. How hard a mod is it and will it restore my factory steering wheel temp controls (on 98 Navigator) I lost with the radio upgrade? Anyone?
