head unit questions

I am sure it's all been posted before but I didnt find anything.

I am looking into possibly replacing my stock head unit with a double din dvd/nav unit. any suggestions as to which one to buy? I am worried about a few things.

1. I would like to continue to have the use of my rearview cam on the mirror or unit. Is there extra parts involved?

2. I dont want to lose the function of my steering wheel controls

3. whats the market like for my exsisting xm tuner and and fit kit?

Thanks in advance fellas

 

I have a kenwood dvd/nav unit. It also has bluetooth. It also has the rearview cam on the unit and the mirrow. I lost the funcion of the steering wheel but i think they make something where it would work. Not sure about xm tuner. Dont have one

 

How did you get the rear view to the head unit? same or second camera? How is it wired?

 

they splice into the feed

 

Check out the Rosen units, looks like tacoma is coming out soon. I think I'm going to have to get one. I think they maintain all functionality of stock parts and looks like stock. Very nice looking units
