i looked at a couple of older threads about 2.5 roadster compatibility but did not get a clear sense of what worked and what did not work. can someone tell me if i replace the original 30-pin cable that came with my roadster with the newer lightning connector cable, which (if any) of the following will function: charging the iPhone 5s? wired audio to the alpine singeDIN head unit? (as opposed to bluetooth which i presume will not be impacted either way) other functions/controls for playing and displaying music tracks? i mostly care about the charging but am curious about the rest. i apologize if this is already covered in another thread that i failed to locate. thanks!
