Thanks for the information.  My biggest worry about installing an aftermarket system is what happens when I do something stupid and break the retractable antenna.   Currently it is very easy to replace however the process requires a few control functions on the original radio to be pressed simultaneously.  Can this sequence be replicated with an after market unit?  If not,   Is there a way to replace the antenna if I switch?

Does anyone know if you lose the “mast removal” function by replacing the factory radio in the sc430?
