Just wondering how people are finding the 330 units, seriously thinking about upgrading to one soon
Still using mine, had it since October 2016 and it's a cracking unit for the money (about £90 these days including shipping) - quick to startup, touchscreen is responsive and it does exactly what I need which is just to play music from my SD Card. I highly recommend it to those looking to add more features over the stock RCD300/RCD500 units while retaining the OEM look.
If you have an Apple iPhone you might want to spend a bit extra for the Apple CarPlay version for additional features like Map Navigation and iTunes integration, a bit pricey from the original RCD 330 but it's still price competitive when you compare to an aftermarket Double-DIN stereo with Apple CarPlay which is almost double the price (anywhere from £300+ without a fitting kit such as fascia's, adapters etc).
