GPS & the Wizard problems CPU crawls very slow

[cyber16]

Hello all.
I have a Cingular branded 8125.
At this time, I have Molski's 3.0.0.0 AKU 3.2 Rom loaded
I have also tried to clock the cpu to 240mhz

It seems the phone does NOT handle multi tasking very well.
The gps works well if you do not ask the phone to do much such as make or take a call. At times even without calls on over the phone while the gps is running. It just starts to crawl very slow, screen re-draws become very slow.

I have tried several GPS applications that run just fine on normal pda's such as the Dell Axim x30-x51v line, these all have 624mhz cpu's.
I have even used these gps applications on the Dell Axim x5 300mhz pda with a Socket Bluetooth cf card without this problem.

My main goal for this phone was to have both, mobile phone with mobile gps

Does anyone have a suggestion on my next move?
I use Bluetooth gps receivers and the software I have now is:
iGuidance 2.1
Dell NavteQ GPS
Belkin GPS "similar as the Dell"
PocketMap Navigator R3 3.12 USA
MS Streets & Trips 2006

Try a Molski AKU 2.x rom and watch the difference. iGuidance doesn't like AKU 3.x. It's not the GPS unit because the spoken directions kept up with the positioning, it was the graphics that wouldn't move at all or, if they did, once every few minutes. You can use AKU 3.x or you can have working GPS software, your choice. Also, note that iGuidance is now up to 3.0.1.

I've been using the OnCourse 5 system with a BT-339 SiRF-lll receiver. I usually overclock my 8125 to either 228 or 240 while using the receiver and mapping software. I'm also using Molski's 2.26 30MB ROM.
One other thing I do before firing it up is that I disable all my other Today plugins and reboot -- loading ONLY the navigational software. This seems to free up the resources needed to not only run the GPS, but to also handle phone calls, as well.

However -- YMMV -- depending on how much available memory your phone has otherwise.

Thanks for the input.
Looks like I shall change roms to Molski's 2.26 and give it another try
