alpine nav

[kennymacleod69]

hi guys am new to mercedes, i have a 2001 e220 cdi avant auto. i am looking for some information about the speed pulse wires found in the pass footwell. i used a speedpulse finder on the 3 green wires, but have found all the pulses to be too fast? at 20 miles an hour the alpine nav reads about 156mph, which inturn crashes the nav . i had this system in my old car which was a mk 3 golf 2.8 vr6, connected the speed pulse and it worked perfect. any info is greatly appreciated.

Which system do you have?

I have installed countless amounts of Alpine sat navs in loadsa diff mercs without problems, are you sure you have the correct wire? use the one from the back of your ISO plug.

thanks for ur reply, the system i am using is IVA-D310RB & NVE-N099. i could not find a speed pulse in the iso plugs. if possible can u tell me the pin number and colour of wire i should be looking for? is there any possible reason why the nav is picking up the pulse wrong? the speed pulse tester was also picking beeping alot faster than normal, cheers kenny

kenny, this has been covered before, a little search normally answers all your questions

FYI, im using the exact same setup and it works fine. In fact its the best sat nav system on the market and is spot on!

Got to agree about the system its first class. I know it doesn't do speed cameras - but then i am not too concerned about that as others, i want one system that does Sound and Navigation - and this does it.

Remember to get it to recalibrate to the new wheel size, in fact they recomend you do this even when you change tyres. Takes about 100m to resynch the estimated speed to the pulse and gps fix that it does about every 9 seconds. Once that is done it should be bang on. The sync should be done when doing a longish route that you are doing on the sat nav - so it can compare what it thinks you are doing speed wise to what you are actually doing from the GPS fix.

cheers guys, i have to agree the system is great. i will try connecting the pulse again and give it some time to calibrate, but because of the speed difference it was freezing the nav. will keep u posted of whats happens, thanks alot, kenny

you did say yo took the pulse from the footwell?, take it from the ISO plug, you may have the wrong wire!

i couldn't find one in the iso plug, my friend knows the alpine rep so he looked up where the wire should be and it was him that said it was in the footwell. i have connected it again and calibrated the system, after about a mile it is reading the pulse and working nearly perfect, it is still about 3 mph out, but i think it should cure itself. about 100 miles to properly calibrate? thanks for all ur help.
