I know I'm joining this thread a bit late but I wanted to ask you if you or anyone else produced looms for sale?

I'd like a loom to inject a different image onto my Lexus Sat Nav screen using a converter from converters.tv.

How about a loom to allow AUX audio input?

With all the plugs prewired ofcourse.

i have been making lexus wiring harnesses for years for lexus factory cd changers and navigation system add ins. the toyota cd changer port not only has different pinouts but only has 1 set of communication lines. the lexus has 2 and sometimes 3 sets. those are the txm- txm= txs- txs= wires on the schematic . so there is no way the lexus headunit is going to recognize a toyota cd changer adapter input. blitzsafes toyota adapter does not work on any lexus. they made some for lexus model but  had no idea that every lexus has a different wiring relation with the amp and headunit. they pulled the lexus aux adapters almost immediately after releasing them several years ago. even the ones that seemed to work initially started cutting the sound out every 7.5 seconds which was the communication line interference from the cd changer  to the headunit correctly................................................................. it appears the lexus factory  navigation system headunits on the 2001 up models are easier to add in dvd and xm radio but that is still in the experimental stage in the usa but has been done on the 2001 ls430 that i know of. with headunit controlled through the cd changer port. the screen reads out disc and track numbers but they represent the station number when xm hooked up. so station 120 reads disc 1 track 20. .  so it is possible to make a direct connction to the headunit on a lexus that is for sure. the 2005 ls430 is finally xm compatible from the factory.

How did you get on with the AVElectronics unit in the end? Id be really intereted as there are rumours that it doesn't accept PAL inputs into teh unit. What was your experience?

Thanks for the responses.  I was getting the NAV up while it was wired through the tuner, and while the connectors are not RGB in themselves, I could disconnect them and lose different aspects of the signal, so I unfortunately couldn't blame it on anything to do with that signal.  Turns out that even a momentary touch from that wire to a live 12V feed would blow the unit (kinda obvious) and as I was being careless, my best guess is the stripped end (all the wire were pre-stripped) hit one of my live fuses in the panel.

I'm shipping it back for warranty...they'll let me know what was up with it.  So...while that is out, I'll be working on adding some switches to my steering wheel.  lol  Not sure if it will be best to go wireless, or disassemble the steering wheel/column and see what I can do in there.  So much to do, so little time.  Maybe I'll get started on building the computer, not sure where to mount it yet.

Ah well.  Thanks :)
