I recently bought a second hand RNS-E for my S3 unit works perfectly well in the car ( just need to tell car it is there lol ) but my problem is i am after either a hard copy or an E-copy of the manual for this unit ( has media button 32sd card capacity ) so has anyone got 1 or could they point me in the direction off where to find online as it is becoming like the X Files is it out there cheers in advance
