ive had mine for over a year now sound is better than standard, satnav is fine never crashed also the handsfree works brilliantly
bad points satnav can get annoying muting it will mute the music aswel, aftermarket headunit such as pioneer u can mess with equalizer settings the erisin only has preset ones
freeview only works when stationery but only in high areas works wonders otherwise
good points wiring is a doddle straight fit u also have all the rca ports for aftermarket speakers, subwoofer, you can connect iphone 4s to it via bluetooth and play music through blutooth no need of the ipod cable doesnt supports iphone from 3gs onward but does charge them up
the one in your link is the latest model so should technically be better but idk
mine is the old interface so i slightly different but has everything the same apart from the canbus kit as before they only sold them separately
personally id go for pioneer or alpine better sound quality but feature wise this does the job fine
ill get sum pics up by the weekend
