Just wanted opinions on using "ZIP scanner" to program my BCD436HP. Unfortunately I'm unable to program my BCD436HP myself with sentinel, I live in a rural area with no internet providers I'm at the mercy of t-mobile internet wich is spotty at best. Having said that, I was thinking about ZIP scanner to do the programming for me.The programming will be on a SD CARD wich all I would do is put SD CARD in scanner and boom there it is. Is it that simple? They will charge (of course) , my question is, has anyone here used ZIP scanner for programming? If so, was it, is it worth it? Also would the latest upgrade be included? Any opinions or suggestions is greatly appreciated.
