It's a fairly good fitment, but not completely perfect! But then again I doubt there's many (if any) which are and could live up to my standards lol.
The appradio however sounds better on paper than it is. IMO there aren't enough apps which are compatible and most of them cost money. Also you can't use apps over Bluetooth so you have to plug your phone in every time you want to use them, which for most people with music on their phones shouldn't be a problem but for me however I use an iPod nano for my music so is rather annoying. What I didn't realise about these thins is the cost of it all, the unit itself i got for £200 but the interface is £35, £14 for the fascia, £10 for the patch lead, £15 for the line booster (2 if you want front and back speakers boosted) plus postage on all that stuff so say another £5-10 it all adds up! I make that just under £285 and £85 of that being relatively hidden costs if you don't do your research first!
