The holux 236 is a good receiver. I used it for about 6 months before I dropped it and broke the on/off switch (doh!)

Now, I'm using the i-Blue 757. It works every bit as good as the Holux 236 as far a signal acquisition/strength. However, the killer feature of this unit is it has solar panel charging. The unit is slightly larger than the Holux, but I have charged this thing exactly ONE (1) time since I got it back in march. I just leave it on my dash unpowered and it charges through the solar panel. It has auto BT signal detection so it powers way down when the phone is not present and only powers up when a GPS app makes a call to it's assigned com port.

Just my 2 cents... good luck w/ your search.
