This is for all the guys with factory fitted double din systems, or even single din (retro-fit) that are considering the RNS-E.....some help from RNS-E drivers please what are the major benefits of the RNS system, apart from DVD navigation (which i dont think will be as good as tom tom) is it worth £400 - £500?? how does it integrate with other add on in car such as bluetooth (can you scroll through phonebook, and access menus from phone)?? will the 6-disk autochanger still be compatible?? at the moment mine is behind the dash but i think its buit into the factory fitted and cannot be seperated, is this true? does it work with DIS at all? im assuming it function with MFSW, as you would expect volume, station search etc.. does it work with ipod?? and i think it also has television function...does this require anything other than a antenna? 1 more thing, will the bose system sound the same quality, does the RNS-E connect with bose?? sorry for the long posting, im sure it will benefit a more than a few heads out there.
