Intravee II/spec dock install

[H8Rain]

Sorry, another question. I run a program on my ipone called Pandora Radio http://www.pandora.com/ This is a really cool streaming music app that runs through the iphone (you should check it out, it's FREE).

This app. customizes itself to my music preferences based on the feedback I enter when songs are playing, which means I will want access to the iphone. Trying to hit a button when it's in the spec dock will be too difficult. So I'm thinking of just running a cable from the armrest box and setting the iphone on the top of the tamber door over the cup holders. Thats usually where I put the phone now and it works great. The rubber protector keeps it from sliding around, plus I have a full view of the screen.

So my question is..... instead of ordering the spec dock, could I just order a 2' cable (along with the 6' cable) to plug into the charge converter (instead of the spec dock)? I know this is not the most intergrated way, but I think this will offer the most flexability.

Thanks
