I have to say this was sooo much easier this time around since fitting the ISO plug. It has bluetooth handsfree, radio, CD, MP3, USB connection, IPOD connection, digital TV (though I have not set this up, it does not come with the DTV aerial in the box you have to buy it separately), and sat nav - comes with a UK map smart card so if you were to take it abroad you need to buy the specific sim card with those maps. Also has a remote control which is now thrown in my glovebox, can be set up for reverse cam and a number of other features. Comes with a touchscreen pen but finger touch is fine, I think it would be difficult to use the pen whilst driving! I have to say, for all the trick stuff this headunit does and for the money it costs it is VERY good! I was looking at Sony and JVC units with similar spec and they are around
£800+. So I would say this is quite a bargain. Oh btw just for the record, remember when I had the battery drain issue and I thought it was my funky stereo wiring
`skillz`, turned out it wasnt, it was a drain from the old steering fogs which JDM have since removed for me when it was in for respray.
