Hello folks,

I recently rewired the old carphone (Nokia 6090) back into the P38 and on installing a shiny new sim card this evening I am happy to report that it is up and running.

However, the paranoid security system doesn't seem to like it as it has been ignoring the key from then on, requiring the eka code each time.

When re-installing the system I relocated the main module in the rear off-side wing cavity, near where the security aerial receiver lives. So I suspect that the signal is swamping the security system.

This phone has been fitted for some time before my ownership and the phones module was previously tucked down beside the sub in the near-side rear wing area. WOuld that short a distance really make that much of a difference? Or could the loop of aerial cable in its new location be creating some sort of interference?

Regards,

Smiler.

Even though they're not on the same frequency, you're putting a transmitter right next to a receiver which is famous for its inability to screen spurious signals.
Moving the phone base unit and aerial back where it was and testing it will give you the answer!

Pull the power to it and see if the key starts working again :)

Tomorrows job then. Though the complete re-location and re-wire will have to wait as I have a garage to clear and an Essex lump to pull from the yellow Scimitar.

Surely if it’s wired into ignition switch, so only on when your in the car would cure the problem if it’s as said, signal interference. No power, no interference,

That would do it Chris, but on the other hand, a phone that only works when the ignition is on might be a bit frustrating.

Looking at the spec, the Nokia 6090 whomps out 8 watts which is enough to saturate a receiver next to it

This kind of stuff is Gilbertd's area of expertise. Maybe he'll have some ideas, when he stops to take a breather on his latest road trip.

The 8 watts quoted in the Spec. OB is a maximum value (ie. when at some distance from a GSM Base Station). It could still be in a "standby" mode with the ignition off Smiler - but definitely overall not a good idea to co-locate it near the iffy P38 Receiver as others have already said....!
It was probably installed on the other side because of this and yes under these circumstances a few feet can make a difference. Where is the phone antenna located ?

My looking at it is, if I’m not in the car , it might as well be turned off, coz I’m not gonna answer, lol

It was all rewired by myself in accordance with official installation instructions as the original 'professional' installationwas appaling.

It only powers on when the ignition is on. The problemis when you turn the ignition off; it takes time to power down. So when you then press the key-fob to lock it the receiver is being swamped by the phone signal as it shuts down. If I turn the phone off before turning the ignition off it is fine.

I shall re-locate the control unit back to the other side, only in a better manner than the previous effort.

Aerial itself is located on the roof near the back.

I’m actually amazed it still works, ive had a few with a phone system, I’ve always just ripped them out. My one now has a roof Aerial from a phone system, I’m going to use the hole to fit a better radio aerial..

No time for a breather but I'm here now. Blimey, we are talking geriatric old crap that should have been to the nearest WEEE recycler years ago here. What's wrong with Bluetoothing to the stereo? As said, a car kit with built in transmitter next to a receiver with a barn door wide front end and the selectivity of an Essex girl after a night on the town, is asking for trouble. If you insist on using it, mount it as far away from the fob receiver as possible (inside the left front inner wing would be good)......

I used mine for a VHF aerial, since it's got a standard Panorama base. I just swapped out the little 900MHz rubber duck for a 145MHz whip.
