I Just ran across this thread...Ancient for sure...The answer is that one CAN install an OEM navigation system in a non-nav car. I have been doing just that for 15 years and counting :)
First off... Welcome to the LOC :) Yes, One can install a nav into a non nav car, If you decide to go OEM let me know as I have all the parts needed for the install. TIA
Does the engine turn ? Is the battery fully charged ? Clicking when ignition is turned on ? We need a bit more info for an over the net diagnosis. TIA :)
