hi all. new here and found this place while i was researching what unit to get. lots of great info, thanks to everyone who contributes.
one thing i found was there is not a lot of install pics (during install) so i figured i would help out anyone who is going to do an install.
here is the final product:

i went with a Boyo VTL-300 backup cam and love it. great picture, sturdy metal unit, $160 shipped, super easy install, works great at night (with the reverse lights i added you cant tell day from night), what else can i say. bought it from 'barneyselectronics' on ebay, they shipped it fast and i had no problems.

here is the image:

here is where i mounted the xm box:

and here is the xm antenna. first i tried leaving it on the metal bar under the dash with the GPS antenna but the reception sucked. it works great on the dash here.

its kinda tough to see, but this photo is of the area just to the drivers side from where the head unit mounts. i put the USB box here and that metal bar you see is where the GPS antenna is mounted.

heres where i ran the USB wire so i can just place an ipod/mp3/flashdrive in that storage area.

heres the mess with the dash removed

overall it was a pretty simple install considering how complicated the system is. the biggest trick is managing all the wires and keeping it somewhat professional. i used a TON of zip ties to keep everything neat and organized.
i tapped into the VSS right there in the harness for the stock radio (gray/black) and tapped into reverse in the rear of the fuse panel under the steering wheel (black/pink). for the reverse wire it took some time to find the right one. there are 3 black/pink wires in the back of the fuse box. it was the one on the upper right connecter if you tilt the fuse box down and look at the back (so when installed normally it would be closest to the brake pedal).
there is an empty grommet on the firewall just under the main wiring harness passthrough. dont know what option you may have that this would be used, but on my F250 powerstroke lariat it wasnt used. i popped it out, cut a split to run the camera wire through and was good to go.
i also installed infinity reference speakers (crutchfield has them on sale right now) to replace all 4 stockers and they sound great. i couldnt believe how easy it was to install them either!
im still waiting on the peripheral peswips adapter i ordered off ebay b/c i couldnt find it locally (never buy from 'allbestparts'! its been almost 2 weeks and i am going to file with ebay b/c i paid immediately and his auction said he would ship within 48 hours. he wont return my emails either asking for a tracking number or info on my package!!
). that will complete my avic install.
after that, all i have left is to buy, build a box for and install one or two shallow mount pioneer subs (tried to fit my fosgate punch 10s but there just isnt room in an f250 crew cab
) and i will be good to go.
thanks again to all those that contribute to this forum! and i cant wait until we finally figure out the bypass ![]()
feel free to ask me any questions about an F250 install!
