thanks folks for the "balanced" discussion,
i had just ordered an AVC through rob apparently a new shipment arrives tuesday which has the usb port on the front.
Rob was very honest had mentioned that some people have had trouble but a new head unit had been sent up to help investigate the battery drain.
so no blab blab blab sales talk he appeared to be right behind his product

after reading the current thread and going to all the other sites, i thought id done the wrong thing, but getting a balanced view restored my faith.
Im fully aware of you get what you pay for.

Thanks again, and keep up the good work and i appreciate the experience out there
regards
Phil.
