Replacing NB head unit with a 1 DIN ISO radio

I’m loving my 2005 NB but not really enamoured with the look of the standard 2 din radio/cd/cassette unit. I’ll probably swap it out at some point with a 1 din radio in a fascia adaptor with a storage compartment. Not a pressing issue as listening to the engine is music enough :grin:

I’m not keen on hacking into the existing wiring and there’s a lot of confusing info on the web about adaptors. Could somebody please point me in the direction of a wiring harness adaptor that would allow me to plug a standard ISO 1DIN radio unit - Sony, Panasonic etc - into the existing harness? Thanks in advance.

As below, your favourite auction site do them too most likely at a lower price

Thanks!
