Honda Civic 2008 1.4 new 2 din or 1 din?
 

Hey all....am very new to this site.
Could somebody please let me know the most cost effective way to replace a factory fitted 2din headset on my civic?!?
I would like to replace like for like but with a few more features and something a little more aesthetic than the factory fit but it seems more than a little complicated. Or even go for a 1 din with a fascia and extra pocket.
Can somebody please tell me what leads/adapters are required to complete this install and or if it's possible to wire an amp and sub to the existing factory fit thereby eliminating all need for the new fit.
A big ask I know but all that I am reading on line is all very conflicting and seems to come from American sources with fittings very different to our own in the UK.
Please help!
