Hi
I have just had the above radio installed in my Prado and am having some trouble with it or maybe a lack of understanding on how its supposed to work.
Main problem seems to be that the conversation either comes from the handheld speaker separately or conjointly with the hand held and the unit behind the dash together or just from the speaker behind the dash.
Also it does not seem to transmit on occasions.
I have discussed this with the auto electrician and he advised that he installed as per specs supplied and seemed to be ok when he tested it.
I am not savvy with this sort of stuff so if anyone can give me some advice it would be greatly appreciated.

There must be a mode selection activated to select one speaker HH, or both or the other indash only.
Possibly pushing buttons is changing it's mode of operation. Maybe, find that button and don't tough it when set.

When transmit is working, there should be a symbol on the screen to show. Is that always working or is it sometimes not active when the TX/PTT button is pushed?

If you push the PTT button and it doesn't work, ie no change on screen, then you may have a faulty PTT button, Mic lead or connection to the unit in the dash.
Give things a wriggle when you transmit to see if it drops out or in of TX with the fiddling around.
You may discover the area where the problem is, or the situation which causes it.

You could check your plug connections. Pull them apart and then re-mate them making sure they go right home..

Howard,

From what I can find on this model, it seems that both the speaker in the base unit and the speaker in the hand-held unit always operate simultaneously. There is no option. Uniden use the phrase "Dual Speaker with Synchronised Volume (Speaker at Base and MIC)" which seems to support my findings.

Cheers
Allan

That's right Allan, no options, the sounds comes out of the hand mic speaker and the unit speaker.

I have my unit mounted on the trans hump just out of the way of my left leg, so I get the sound clearer from there . . . but also there's a jack in the unit you can plug an external speaker into and place a good aftermarket speaker on the dash or wherever.

Makes things a lot clearer :)

As for transmission issue.
I haven't had any problems with mine (3 years), suggest check handset connection to unit to see if correctly attached.
Then get a hand held and a wife / mate, and give it a good testing.

If the handset or unit is faulty, I suspect the Auto Elec wouldn't be the one to talk to, but the retailer from where it was purchased.
