buy a portable one, nuvi 350 works great. $399. thats it. buy an e70 with all options you listed. well, i am not putting any more $ in the e53 as the e70 came out. anyway, i believe some members did install the pioneer which includes everything you list. do the search. i think it will cost you around $2k installed. again, nuvi 350 works like charm and i could take it anywhere, any car.
