Sorry, I should have been clearer - That's a totally different, far inferior unit (hence the price!).
I was talking about this one: http://www.fusioncaraudio.com/north-and-south-america/marine-audio-2/stereo-units-15/msip500-56-product.aspx http://www.fusioncaraudio.com/Libraries/Fusion%20Gallery/MS-IP500-secondary.sflb
This unit is one I install in almost all customers boats now when they change out their deck. Previosuly we used the Clarion, Kenwood, Sony, Alpine and Pioneer gear but I have since got rid of all that (bar a couple Sony iPod units) and try and stick to this unit exclusively.
One point I would agree with on the review you saw though was the ipod sleeves... I agree that if you have different iPods to use then you will need to select a different sleeve to change over... but to be fair, this takes all of 10 seconds (less time than it takes to take a cd out, put the cd in a case and get a new cd out, remove it from the case and insert the cd)and how often do you guys change iPod when out on the boat? I just have a Boat/car ipod and just carry it between the 2 vehicles.
Hope that clears it up.... If you have any more questions feel free to chuck them at me... I don't represent Fusion, but I am a dealer in the UK so can offer unbiased advice based on my experience.
