my avic n1 was modified when i bought it .it currently works while driving.this was a few yrs. ago . i wish to upgrade to 2007 software (off ebay) and want to know if
i will still need to solder my unit to make it work or if it already is set to work, with whatever modifications were done to it the first time?
thanks
