I've done a lot of reading regarding iPod hookups and I've come down to the Ice Link Plus and Blitzsafe. However, it seems like there's good and bad comments with both units and it seems like eveyone has a different answer in regards to the functionality of the units. To help me decide which one I should get, I have a few questions. I don't mean to sound like a jerk, but please only answer if you have either one of these units. I prefer straight answers rather than guesses/"to my understanding" type answers. That just makes things more confusing and complicated. Thanks.

1st of all, I have a 2005 TSX with NAV.
Questions:

1. Do i need to purchase any other accessories/parts to have either of these work with the nav system?

2 a) which one will allow me to use my steering wheel to control the iPod?
2 b) what can i control with the steering wheel?

3 a) which one will allow me to use my factory nav stereo to control?
3 b) will i be able to control the iPod with the touch screen?
3 c) what will i be able to control with the nav stereo/screen?
3 d) To my understanding, I can forward from song to song with the stereo/screen. If I select random and then press the forward option will it jump directly to the next song, or will it randomly select the song?
