  • Pioneer DEH-S4000BT Car Stereo is rated 5.0 out of 5 by 5.
    Rated 5 out of 5 by from Excellent sound quality I've had this product since Christmas and have found it to be an excellent bit of kit. I use it mostly to listen to Spotify using Bluetooth and it works a treat. The hands free is also useful. Much better sound quality than many built in similar products that come as standard in many modern cars.

    Rated 5 out of 5 by from Quite impressed Nice stereo only problem is the screen could do with being brighter. The hansfree is really good quality. Menu system is easy to under stand also the front pop off facia can be tricky but all in all a really good stereo

    Rated 5 out of 5 by from Quality bit of kit Just bought this stereo last night had a pioneer radio in my tractor but needed hands free, this was a great choice, the unit itself was almost a plug and play, the old unit was out and plugged in I les than 5 mins everything working in another five mins noticeable better quality sound than the old one radio 1 4 and Scotland already tune in in took about 20 mins too install the mike cable to the front right hand pillar due to the route it had too take. Had to be very careful pushing the unit into slot as was a lot deeper so had to be careful not to pinch any cables especially mike cable as there is enough cable to go about anywhere in the cab. Now too the the results absolutely so far 5star item made 7 calls to different people and asked them to phone back easy two way conversations no one New I was on hands free very clear I have to say I would put it as least as good or not even better than my hands free in my dmax pickup A quality unit with to my mind extremely good value for money this is in a tractor!!

    Rated 5 out of 5 by from Great unit Wanted a bluetooth and cd unit in an old Freelander and this seemed to have all of the features (except DAB but that's a different, more costly story). Unit fitted in minutes as I had a bmw to iso adaptor fitted, Land Rovers of that age use the same big head unit connector as bm's. Ran the mic cable under dash and up A pillar in no time, wire was long enough. Sound is good but it would be nice to have some bluetooth 'boost', I like listening to podcasts and they're rather quiet, I have to turn the volume up a lot, not a fault on this unit but bluetooth as a whole (or my phone/me being a bit thick!). Unit has loads of features, I'll have to read the manual and download the app sometime. Some options aren't self explanotary, a scrolling message as to what they do would be nice. Front panel is a bit awkward to get off, it doesn't just pop off, you have to manipulate it a bit. Screen colour is red. I haven't seen any other colour option which would have been nice. It might need a aerial adaptor, unit aerial socket is for a long, deep plug, many car aerials now only have a short plug, my previous radio had one of these adaptors so I was ok. Very happy. Connects quickly and starts playing automatically (there might be an option for this) but I like that it does this. Sound is pretty good and it didn't break the bank.
