I have a 3250 and had a hard time hearing my call and wanted to increase the volume. I used the main volume control on the GPS and also maxed out my phone- are there any other adjustments possible- thanks!
I had a previous phone where there was a separate volume control for bluetooth transmission. Doubtful this applies in your case, but it might be worth checking.
Have you tried connecting it to your car stereo and increasing the volume there?
Thanks- checked both the phone and gps and although I got the volume up on both, the speaker seemed to have some distortion. The unit is not bad on regular roads but the NJ Turnpike is an extreme test.
