I have poor reception on my car radio. Any ideas? The aerial is all plugged in ok as it does make a difference. Would a non-existent ground connection have this effect? I took out an old tape one and put in a shiny Aldi Tevion £40 jobbie (Mp3, Auz, SD, radio cracking deal, remote) and it is still the same. Does anyone have any ideas?

What car is it? Some cars just have a better reception than others. You can buy signal boosters which can help. Some cars even have these as standard, and they stop working when someone changes the head unit because they usually draw their power from it. If it has one of those screw in aerials, make sure its screwed in tight. I would also check to see if it is the standard oem aerial by looking to see if its the same as other aerials on the same model of car, as sometimes they get broken or stolen and some of the replacements you can buy are rubbish. Other than that, I would google for information specific to your car as there might be a known issue.
Its a peugeot 106 (P reg, and its only for work) and doesnt appear to have a signal booster. It doesnt pick up some stations and assumed it was either the aerial, or that the radio wasnt grounded. I know the aerial is as its attatched to the roof, (Its about 2-3 foot long) but the screw that is supposed to go to ground on the back of the radio prevents it from slotting in. If this is needed to get a good reception, i have no hesitiation in drilling and tapping a new hole to fdo this. I was hoping for a quick fix.
I'm not entirely sure what screw you mean, but I am guessing you are talking about the double ended ones you sometimes have in the middle at the back of the head unit. These are not for screwing into your car. You attach a little rubber nob to the screw and it just stops it sliding too far back. You should not need to drill anything to install a headunit.PhillyDee said:
The only headunits I've seen that require grounding aside from the grounding you get from the iso leads, are the alpine v-drive units, and they need a ground because they have a high current lead directly to the battery. If you really think grounding will help, then I would suggest just taping a bit of wire from the back of the head unit to something substantial and metal on your car. That was you can test your theory before you go drilling holes in your car!
gc123 said:if its an audi/v/w /skoda it may require as said a booster as a lot of these send the power to the factory amplifier via the aerial lead.
or if a different make say vauxhall are you connecting the aerial feed wire up to power the amp
Indeed, my Seat Leon requires 12v to be applied to the inner core of the aerial cable to activate its booster, reception is awful if you dont do it, but very very strong when its applied. When fitting an aftermarket stereo i had to bodge it with 12v from the switched supply to the stereo and spliced into the aerial cable.
Yep. thats the one i mean. I was under the impression that it had to go to the chassis ground. So, it looks like it needs boosting. Hmmm. Im not about to start wiring 12v wires to things until i know for definate that i have to.
Thanks for your help folks.

Should be a hole at each corner of the unit that you have to buy the keys for,couple of quid from halfords will get you them.

right guys, i have figured out how to remove it, next problem is connect the new speakers to the new head unit, i have put speaker wire throughout the car from the back to thr front its just there are no connectors on the head unit to connect the cable to, he headunit is a pioneer 6900ib which has an iso connector to it via an adapter, the car did not orginally have any speakers in the back so i take it there is no wiring in the original iso connector so any ideas how i can connect them ??
cheers /sorry for the long confusing post

There will probably be a small diagram on a sticker somewhere on the headunit that tells you which wires are which, or if not, in the manual for the head unit. Just trace these into the ISO block and if there are some wires coming out of it, connect your new speaker wires to that. If there are not, then you will probably have to cut into the wires coming out of the head unit. Just make sure you get the right ones and get the polarity the right way round (ie + to + and – to -).
