Having just got my Eddy, its got an RCD330
Looks like this;

But I want to change it out with something that has Apple car play with a way to route the wire behind the unit as my current wire just gets in the way when changing gears.
At first, I thought about getting the upgraded version of the RCD330 called the RCD330+ which comes to $479 but has more RAM and a wireless Carplay dongle! (Select Package A) but I am yet to see what that comes to with shipping/fees etc think it comes directly from China but is the cheapest option and is plug and play. Only downsides I have discovered with this unit are it has no DAB and the FAM/AM stations won't display the station names, you will only see the freq - As it is build as an OEM replacement, it also doesn't have any pre-outs for amps etc.

This unit was acutally an optional extra from VW so you know its certified and will also work with your climate control etc.
Only downside to this is the cheapest I have been able to find it is around £1,100-£1,400 on ebay and upon reading reviews, has ALOT of complaints about it not being a very reliable unit with the most common issue being lag on the interface, overly complicated menus and DAB not working.
The final 3rd option I have come across is the Alpine X902D-G6 and X903D-G6

This is by far the nicest looking unit in my honest opinion has DAB and Carplay etc and works with all the standard things, I am however yet to find them for sale anywhere...
