decided about 10pm friday night i was going to do this the whole thing took about 5-6 hours which included hooking up the head unit, and running power/pre-out wires for the amp to the back. now i got to make some custom speaker mounts and install the amp(s).

 

hmm, you actually grabbed the speed sensor wire? i just did my avic-d1 in my gs400 a couple of weeks ago and i didn't grab the speed sensor... not because i didn't know how but i didn't want to. its been working fine so far... what is the difference if you tap or not tap into the speed sensor wire? what does it actually do? are you going to hook up an external dvd player to your unit? did you do the parking brake by-pass thing? btw, i see your climate control lcd is going bad?

 

i also have an avic in my gs4 is a z1, i did not connect the speed sens.. did not need to. gps works fine and the speedo on the unit is the same as in the car. i got the stereo kit from carson toyota and it matches the rest of the stock equipment perfectly. check out avic411 for info on all avic units

 

yup, i originally spent $30 on the american international double din kit but i didn't like how it looked. so i spent another $55 on the carson toyota oem double din kit and its perfect! everyone thinks its a factory navi!!!

 

I think its for when you go under tunnels, and cant get a GPS signal.

 

the speed sensor is for when the gps signal is not good, this can happen in tunnels, under heavy tree growths etc. i've had that problem with portable gps units in the past. also the vehicle dynamics will not be as accurate without the speed sensor hooked up.

yeah but i want to get an ip-bus unit so i can control it with the head unit, those things are quite expensive.

yep, works like a charm

nah it just looks that way because of the flash, it's fine.

 

i bought the american international kit, the grain may not match as well as the carson kit but it looks fine to me and i only paid $12.95 for it...

 

you bought it for $12.95? damn i didn't know where else to get it besides ebay and it came out to $28 bucks! crap i got ripped!

 

i got it from million buy
i also got the wire harness from there, $4.95 each, i got two of them -- one for the speaker side and one for the power side.

 

damn i should have searched around here for places to buy before i messed around with ebay! got rrrrrrrriped! oh wells, at least now i got the carson toyota oem double din kit! aint nothin like factory baby!
