With so many people on here (me included) retro-fitting RNS_E this is going to seem a bit like treason, but, what the hell here goes. I am quite disappointed with it. The unit itself looks great (switched off!), but the functionality of it (primarily down to the firmware) leaves a lot to be desired IMO. Cons (In no particular order!): 1) I think I might be on my own with this, but the colour scheme of the CD/MP3 & Radio screens sucks orange and white against a red dash UGH !! It looks like Ive stolen an Astra stereo to fit in my Audi! I' will admit that I have something approaching an obsession about dash colours matching - I have been know to pull apart after-market stereos to put coloured film over button lights to make them match a dash 2)The default screen for the radio is full station list rather than the more obvious memory list so that memory needs to be selected each time you switch on. 3)The default screen for Telephone is the dial a number directly using the wheel screen which I cant imagine Id ever use. It takes about 4 button presses and a bit of a knob twizzle (oh-err) to get to the Phone book screen which would be the most obvious starting menu. I dont think there is any real advantage in the RNS-E phone system over the existing phone prep/DIS system. Certainly not as usable as the Parrot system I had in my last car. 4)The navigation system is way more complicated to program than a TOMTOM etc. I appreciate that the lack of touchscreen is the primary reason for this , but so far I have found it far from intuitive, and miss the full 7 character postcode support and lack of customisable POIs. 5)The playlist display screen is another missed opportunity. The obvious thing to do would be to have the details of the track that is playing shown on 2 lines (one for artist the other for title) to give a better chance of displaying the full string, but instead it actually show less data for the track that is playing becuase the track time is appended to it. I know you can display full track data, but that gives too much info and nothing about next/previous tracks. 6) It doesn't seem to display some tracks correctly in the playlist list screen. The odd one just shows "title" rather than "artist - title" , even though if you display the full track details for it everything is there OK. Pros: 1)It looks neat and the large screen is better for the Nav than my Tomtom. 2)Satnav instructions displayed on DIS. 3)I do like having my MP3s on SD cards rather than on 6 CDs as in my Symphony, updating is way easier, and I like the playlist support, but because of the 400 odd track limit per card. it doesnt even hold that many more tracks than the 6 CDs do. If someone could crack the firmware and make each sections default menu screen user programmable (for option and colour), it would transform the units usability, but as it stands I find it quite irritating and am seriously thinking of swapping back to my Symphony and Tomtom. Im certainly glad I didnt pay to have it as a factory fit.
