Question about STI!

**Road Warrior** · 09-10-2006, 11:59 PM

I understand that STI's latest rev is A4M9, or at least this is for my STI... also I know that STI has had previous revs including A3M8, so my question is: what's different from previous revs to the current one, A4M9, what was changed/added from previous revs to the current one, what did not work with the previous revs that was needed to update it to the current A4M9... TIA

Up to A3M8 they falsed to every single cheapo detector on the planet. Drove me insane. Had to drive around in tech mode and visually check the frequency of every alert to find the real threats.

Do not be an early adopter of new RD technology :wink:

Thank you for reply... where I live (the most populated area in entire Canada) it's a miracle to be around a vehicle with an RD, any RD, but 99.99% of all the institutions around you are built with motion sensors, banks, all stores (Home Depot, Wal-Mart, etc.), beer stores, subway stations, etc, and most of them are on K band, a band that you cannot disable like X band... and my STI picks up ALL stores, banks, subway stations, in other words it falses all the time (in the city)... the good news is that it's very rare to get a Ka false alert in the city and most of the Toronto cops are now on Ka besides OPP that's all on Ka already... so, other reason for updating from previous revs to the current one?

Yeah should have been more specific, they falsed Ka.

There was an overheating problem with the earlier units too. Or rather the internal protection would shut the unit down when it reached a certain temp. Once they cooled down they were OK again. Didn't happen often and I think finally fixed with A4M9. AFAIK

Thank you again... I forgot to mention that I keep it in Highway Mode, X/POP/SWS all off, maybe the H mode is the reason for such a huge no of city K falses, I will do a test with AutoScan Mode to see if it's any difference... my other RD, the S2, which I used for over a year, gave me 1/4 of the falses this STI does it now...

**carbonhed** · 09-11-2006, 12:43 AM

Well Highway is completely unfiltered so that will give you every K band alert. Autoscan runs an intelligent internal screening over X and K that adjust to whether you're in the city or not and City lowers the X and K band sensitivity even further.

I'd be interested in how you get on.

It doesn't cost me a thing to play with all the modes, but the S2, all the time in Highway for over a year, and not even a 1/4 of all this K falses STI gives me so far... maybe STI is built differently, so the H for STI is way more sensitive than the H mode for S2...

**carbonhed** · 09-11-2006, 12:56 AM

Well on the face of it either the STi is way more sensitive than the S2 or the S2 was running some sort of filtering routine that you weren't aware of.

**WRC** · 09-11-2006, 12:57 AM

try city mode, it filters X and K more, but Ka is always at full sensitivity, why not turn x-off is it used in your area?

God knows...

it doesn't bother me at all (only the freaking sound for the STI is baaaaaaaaaaad...), just that I got used with the way S2 used to react all the time... no big deal, I have no problem adjusting myself to the STI :wink:
