It's not just me -- it's many other Subaru owners (search the various forums and you'll see). I actually don't have one on my own car -- no SWCs
I will in my next car.
Advantages of the Axxess ASWC:
- No lag
- Single model works with most cars and HUs (so you can change to a new HU and/or move it into another car)
- In cars with more than 2 SWC wires, all of the wires will connect directly to separate inputs on the ASWC. No resistors needed (unlike the PAC SWI-* units).
- In most cases, programs itself on the first power up (you can also manually program it if you want to change any buttons)
- Less expensive
- Firmware can be updated via a USB-to-TTL RS-232 cable (you must purchase the cable from Metra, or put together an equivalent)
and as far as the harness I got from IAP, there should be no cutting in the original wires (at least I think so)
They're selling off-the-shelf Metra 70-7552 harnesses. That omits the two SWC wires. See my pin-out
for more info.
