Hmmm - good questions. If you're prone to exceed the speed limit regularly, I'd say get the V1 first. If not, then go for the iPod. The reason for hard-wiring the V1 is to hide the unsightly power wire that you'd otherwise have hanging from your V1 down to the cig. lighter. You also may want to look into this if you are getting the V1 - I've had mine for over a year and love it! GL with your decision!
