I was originally looking to fit a proper renault sat nav system to my 03 172 but having had some advice from peeps on here (and seeing it was V. expensive and almost impractical!!!!) i am going to look for a stand-alone type, pda or whatever. I have only ever seen an o2 XDA working and was very impressed. i am obviously most interested in how good it actually is but how its gonna look is v. important to me too. I dont want a head unit type as i would prefer one with some type of graphic display/screen but i am fully open to suggestions. any pics/info would be very much appreciated! thanks
